Method and apparatus emulating read only memories with combinatorial logic networks, and methods and apparatus generating read only memory emulator combinatorial logic networks

Description

TECHNICAL FIELD

[0001] This invention relates to Read-Only-Memories (ROMs) as found in integrated circuits and systems products.

BACKGROUND OF INVENTION

[0002] Since at least the 1970's Random Access Memories (RAMs) made of semiconductor devices have provided enormous benefit to the technology and economy of the world. Most RAMs have the property that they can be written as well as read while in normal operation. Read Only Memories (ROMs) are a form of Random Access Memory not able to be written during normal operation. This invention concerns a fundamental circuit improvement emulating the performance of a ROM based upon its ROM pattern as well as its operation. The invention also includes methods and apparatus generating these circuits and defining their operation.

[0003]
FIG. 1A illustrates the structure of prior art Random Access Memories in general, and ROMs in particular.

[0004] To the inventors' knowledge, all semiconductor memories physically operate two dimensional arrays of memory cells denoted by “Mj,k” in FIG. 1A, where j varies from 0 to 3 and k from 1 to 6. Each memory cell contains a bit of data.

[0005] Accessing the contents of a semiconductor memory is usually called reading the memory. This is the primary and often only function of a ROM. ROMs are typically operated as follows: a collection of address bits denoted as A1-A10 are presented to a row decoder circuit, generating a collection of row decode signals R0-3, each row decode signal Rj enables a row of the memory cell array Mj,1-6 to affect the condition of a collection of column signals C1-6. The column signals C1-6 are presented to a column decoder, which translates their signal conditions into digital signals D1-6.

[0006] The row decoder circuit often includes a collection of two input combiners, each generating four signals. Address bits A1,2 generate, through their two input combiner, the signals P0-3. Address bits A3,4 generate, through their two input combiner, the signals P4-7, and so on. Typically, P0=not A1 and not A2, P1=A2 and not A2, P2=not A1 and A2, and P3=A1 and A2, where not as well as and are logic operators. Exactly one of the four P signals will ever be turned on at a time. By selecting one of these four signals from each group of four P signals, and performing a logical operation anding the selected signals together, the row select signals R are formed. Often the logical complement of the and operator, known as nand is used to generate the row select signals R.

[0007]
FIG. 1B illustrates a typical use of a prior art ROM circuit 100 by an engine 110 providing address signals A[1-N] and receiving data D[1-M].

[0008] The inventors have great respect for this workhorse of the computing and electronics industry. ROMs have played a central role in starting up almost all circuits controlled by or using computers. By way of example, ROMs are found in nearly every computer, modem, disk drive, printer, fax machine, set-top box, DVD player and cellular telephone manufactured today or in the last forty years.

[0009] While memories in general, and ROMs in particular, are the pervasive solution to the providing data for instructions and constants, they possess some significant problems, which will be discussed first from the standpoints of the semiconductor manufacturers, then from integrated circuit (IC) design, IC manufacturing, and lastly IC users.

[0010] The research and development cost paid by semiconductor manufacturers for new manufacturing processes is truly staggering. Each semiconductor manufacturer typically spends billions of US dollars to find and implement even an incremental improvement in manufacturing, such as going from a 0.25 micron CMOS process to a 0.18 micron CMOS process. For fundamental process technology innovations, such as the contemporary work to implement photonic and/or molecular switches, possibly employing micron length optical signal channels and/or nanotube signal tunnels, the cost is far greater.

[0011] Once a manufacturing process has been implemented in a factory, there is a large amount of design collateral which must be put in place before a single computer can be manufactured with that factory. Computers minimally require at least a few gate layouts and ROM's. ROM generation software is needed to take the specific memory data and generate a layout of ROM to be used in integrated circuits. The development and qualification of ROM cells and ROM generation software is thus in the critical path to make the first computers for the new process technology. This is a significant cost, and often a source of delay, for the start of production in many semiconductor factories. What is needed by the semiconductor manufacturers is a way to achieve the function of ROMs without requiring the development and qualification expenses of ROMs and ROM layout generators.

[0012] Semiconductor (IC) product design, particularly for embedded systems products, often requires at least one, and frequently several, ROMs. Each ROM requires a different layout, further requiring design expense to apply ROM layout generation for each ROM. The job of developing a specific IC product often has the generation and integration of ROM layouts in the critical path to generating the completed integrated circuit layout (known hereafter as circuit layout), which is the critical path predecessor to generating the lithography masks, known as the mask set of the integrated circuit. If an IC product is successful, there is often a need to convert the design to a different manufacturing process, which again, often requires new ROM layouts be generated, integrated to provide the circuit layout and subsequently, the mask set. What is needed by the IC product designer is a way to have the ROM functionality without incurring the delays and expenses associated with ROM layout generation every time a manufacturing process is targeted.

[0013] The IC manufacturing expenses to create unpackaged IC wafers are directly related to the size of the integrated circuit being made. While there are various rules of thumb regarding manufacturing cost, it is often at least proportional to the square of the surface area. Experiments by the inventors have shown in certain cases very significant reductions in the surface area of circuitry requiring ROMs. What is needed is a way to reduce the surface area of an IC requiring at least one ROM's functionality.

[0014] The prior art includes an extensive research and development concerning logic functions and operations as well as the implementation of these functions and operations as logic gates. Starting in the late 1940's, it became well recognized that switching mechanisms such as vacuum tubes, relays, semiconductor switches such as transistors and their descendants, and contemporary digital integrated circuits, could be described as networks of logical functions.

[0015] Logic functions act upon one or more logic inputs to generate a logic output. Logic inputs and outputs typically have logic values equivalent to a two element collection including ‘0’ and ‘1’. There are situations in which logic values belong to a larger set. Often these larger logic value sets are described in terms of ordered vectors whose elements are ‘0’ and ‘1’. These larger logic values are sometimes referred to as “multiple-valued” logic values.

[0016] Discussion of multiple-value logics would entail a lengthy digression, but briefly, functions and operations upon these logics can be defined in terms of logic functions and operations on 2 value logic terms. This leaves only the question of what are these logic operations and functions acting upon two valued terms. Note that this simplification of discussion is done strictly to render this document more readable, and not to either explicitly nor implicitly limit the scope of the claims. There are four classic functions which will be used extensively herein, and are defined in the following table.

1ABnot AA and BA or BA xor B001000011011100011110110

[0017] Table One illustrates the classical logic functions and operations of negation, product, sum and exclusive or.

[0018] Two inputs, A and B take on all combinations of ‘0’ and ‘1’. Negation of A is denoted by the column not A. The product of the two terms is denoted as the column A and B. The logical sum of the two terms is denoted as the column A or B. The exclusive-or of the two terms is denoted as the column A xor B. Negation is often referred to as an unary operation acting upon one input.

[0019] Whereas the logical product, sum and exclusive-or operations are often referred to as binary operations acting upon two inputs. These binary operations have the very useful property in their indifference to the ordering of inputs (associativity and commutativity) which support a natural extension of these operations to acting upon more than two inputs. A or (B or C) is identical to (A or B) or C, to A or (C or B), and so on. This is the basis for subsequent references logical sums, products and exclusive-or's acting upon two or more inputs.

[0020] Three other commonly used logic functions-operations are defined in the next table.

2A nand BA nor BA xnor BABnot (A and B)not (A or B)not (A xor B)00111011001010011001

[0021] Table Two illustrates Nand, Nor and exclusive-nor logic functions and operations.

[0022] The nand function is defined by the column ‘not (A and B)’. The nor function is defined by the column ‘not (A or B)’. The xnor function is defined by the column ‘not (A xor B)’.

[0023] As digital logic evolved, differing manufacturing processes favored implementations of different logic functions. By way of example, contemporary mosfet, in particular CMOS logic, manufacturing processes make very good implementations, known hereafter as gates, for nand functions of up to four or five inputs and can be used to implement reasonable two input nor and two input exclusive or gates. An earlier logic manufacturing process, using what were referred to as emitter-coupled-logic (ECL) transistors, did a very good job making gates implementing nor functions of up to twenty logical inputs, but did not do as well with nand gates and exclusive or gates.

[0024] A combinatorial logic network will refer to a network of combinations of simple gates connected together so that inputs of the network provide inputs to at least some of the simple gates, and their outputs flow toward the outputs of the network as a whole, possibly through acting as inputs to other gates in the network. Combinatorial logic networks do not possess “loops” causing the effects of a network output to “feed back” into the network.

[0025] In the early periods of digital manufacturing, the wiring of gates built out of relays, vacuum tubes, transistors and printed circuit boards holding modules of such components, was done by hand based upon a wiring list, which came to be known as a netlist. By the mid-1980's a netlist language standard known as ‘edif’ had gained industry acceptance. Generation of layouts of printed circuits and integrated circuits became largely automated tasks of ever increasing subtlety, culminating today in extremely sophisticated multiple wiring layer products at both the system product and integrated circuit level.

[0026] The 1980's also saw the development of circuit specification languages such as Verilog and VHDL, which support event driven simulators. Concurrently, the synthesis of logic functions into gates and customizable gate networks, known variously as Programmable Logic Arrays, Gate Arrays, and Field Programmable Gate Arrays reached a new level of automation. It widely became possible for someone to specify a logic function and define a combinatorial logic network that would perform that function. One well known example from this era is known as “espresso”, which was developed primarily at the Berkeley campus of the University of California and documented in a book entitled “Logic Minimization Algorithms for VLSI Synthesis” by Brayton, et. al., (c) 1984. The research of the time into synthesizing circuit descriptions also provided a second major result, circuit synthesis tools such as those developed by Synopsis, Cadence, and others which translate versions of event languages such as Verilog and VHDL into optimized networks of gates targeting specific manufacturing processes and gate layouts.

[0027] By the mid 1990's hand derivation of logic networks and their layout largely became obsolete. By the end of the twentieth century, committing an integrated circuit product design to production largely became a matter of synthesizing the product's logic, except for memories. ROM designs, in particular, require specialized layouts and their generation is always in the critical path to making a product's circuit layout and mask set. RAM layouts can often be pre-ordered, but until every bit of the ROM is committed, the ROM layouts cannot be generated.

[0028] To summarize, semiconductor manufacturers need a way to achieve the function of ROMs without requiring the development and qualification expenses of ROMs and ROM layout generators. IC product designers need a way to have the ROM functionality without incurring the delays and expenses associated with ROM layout generation every time a manufacturing process is targeted for an integrated circuit. What is further needed is a way to reduce the surface area of an IC requiring at least one ROM's functionality.

SUMMARY OF INVENTION

[0029] The invention addresses at least all the above mentioned needs found in the prior art. Semiconductor manufacturers can provide the function of ROMs without the development and qualification expenses of ROMs and ROM layout generators. IC product designers gain ROM functionality without incurring the delays and expenses associated with ROM layout generation every time a manufacturing process is targeted for an integrated circuit. Often these new circuit layouts are smaller than the emulated ROM's layout, lowering unpackaged IC wafers costs, leading to integrated circuit and systems product cost reductions.

[0030] The invention includes combinatorial logic networks emulating a ROM known herein as ROM Emulator Combinatorial Logic Networks (RECLN). The RECLN receives at least two address input signals and generates at least one data output signal to emulate a ROM receiving the same address input signals and presenting essentially the same output data signals.

[0031] The invention includes an emulation method for the ROM, receiving the address input signals and generating the data output signal(s) by performing combinations of logical operations upon the received address input signals.

[0032] The invention includes methods and apparatus generating synthesizable RECLN descriptions, as well as, circuit descriptions, netlists, circuit layouts, mask sets, unpackaged integrated circuit wafers, integrated circuits, and systems products using the synthesizable RECLN descriptions and products derived therefrom. The invention also includes method and apparatus for doing business involving generation of synthesizable RECLN descriptions and/or the above mentioned derived products. The invention also includes creating installation mechanisms for synthesizable RECLN generation methods to create systems generating synthesizable RECLN descriptions.

DETAILED DESCRIPTION OF DRAWINGS

[0092] The invention includes combinatorial logic networks emulating a ROM known herein as ROM Emulator Combinatorial Logic Networks (RECLN). The RECLN receives at least two address input signals and generates at least one data output signal to emulate a ROM receiving the same address input signals and presenting essentially the same output data signals.

[0093]
FIG. 1C illustrates an RECLN 200 including at least an output generator collection containing an output generator 230-k for each data output D[k] receiving 202-k at least some of the input signals A[1-n] and possibly receiving 224-k at least some shared signals 220 from 222-1 and/or 222-2 shared signal generator collection 220.

[0094] A collection of input signals A[1-n] are received and presented to an output generator 230-k for each D[k] of the output signals D[1-m]. Each output generator 230-k consists essentially of a first combinatorial logic network, each receiving the generator input collection 202-k and generating the data signal D[k]. The generator input collection may vary for each output generator 230-k. Generator input collection signals 202-k belong to an internal signal collection including at least the received address signals A.

[0095] The invention often preferably includes a shared signal generator collection 210 comprising at least one shared signal generator receiving at least one member of the internal signal collection to create a shared generator input collection and generating at least one shared signal 222-1. In these circumstances, the internal signal collection further includes all of the shared signals 220. Often, the shared signal generator collection 210 preferably generates more than one shared signal, 222-2. Each generator in the shared signal generator collection 210 receives at least one input from the internal signal collection, which may include input from received address signals 226 and/or a shared signal 228.

[0096] At least one of the shared signal collection 210 members is included in the first combinatorial logic network of a first output generator and in the first combinatorial logic network of a second output generator.

[0097] Note that these output generators consist essentially of the combinatorial logic networks. Additional circuitry may be incorporated into one or more output generators which are essentially invisible to the normal logic operation of the output generator. Examples of such additional circuitry include, but are not limited to, substrate biasing circuitry, power distribution network circuitry, noise suppression circuitry, and built in test circuitry. Built in test circuitry may include additional signals operationally used only testing conditions, such as product term separator signals for programmable logic arrays, and scan path control and data signals. Note that scan path circuitry may include buried registers, which are passive during normal operation of the RECLN 200.

[0098] The invention further preferably includes at least one the first combinatorial logic networks implemented as one of the following: at least part of a gate array, a standard cell network, a custom logic cell network, at least part of a programmable logic array network, and at least part of a logic cell array network.

[0099] By way of example, the following logic equations summarize various combinations of circumstances contemplated by the invention:

3D[1] = A[1],D[2] = not A[1],D[3] = A[1] and A[2],D[4] = A[1] nand A[2],D[5] = A[1] or A[2],D[6] = A[1] nor A[2],D[7] = A[1] xor A[2],D[7] = A[1] xnor A[2],D[9] = Mux(A[1], A[2]; by A[3]),D[10] = not Mux(A[1], A[2]; byA[3]),

[0100] Note that Mux(A[1], A[2]; by A[3]) provides A[1] when A[3]=0, and A[2] when A[3]=1.

[0101] By way of example, the following logic equations for shared signals Sh[1] and Sh[2] summarize various combinations of circumstances contemplated by the invention:

4D[11] = Sh[1],D[12] = not Sh[1],D[13] = Sh[1] and A[2],D[14] = Sh[1] nand Sh[2],D[15] = Sh[1] or Sh[2],D[16] = A[1] nor Sh[2],D[17] = Sh[1] xor A[2],D[17] = Sh[1] xnor Sh[2],D[19] = Mux(Sh[1], Sh[2]; by A[3]),D[20] = not Mux(A[1],A[2]; bySh[2]),

[0102] Also byway of example, the following logic equations for shared signals Sh[1], Sh[2], and Sh[3] summarize various combinations of circumstances contemplated by the invention:

5Sh[3] = Sh[1],Sh[3] = not Sh[1],Sh[3] = Sh[1] and A[2],Sh[3] = Sh[1] nand Sh[2],Sh[3] = Sh[1] or Sh[2],Sh[3] = A[1] nor Sh[2],Sh[3] = Sh[1] xor A[2],Sh[3] = Sh[1] xnor Sh[2],Sh[3] = Mux(Sh[1], Sh[2]; by A[3]),Sh[3] = not Mux(A[1], A[2]; bySh[2]),

[0103] The invention may also include a propagation delay output generator receiving at least one input signaling start of propagation and generating output-ready for the generated data signals. Such preferred embodiments are useful when the surrounding circuitry supports a self-timed control protocol.

[0104]
FIG. 1D illustrates using an RECLN circuit 200 replacing ROM circuit 100.

[0105] Engine 110 is coupled by the address input signals A[1-N] and by the data signals D[1-M] to the RECLN 200. Engine 110 provides the address input signals A[1-N] to the RECLN 110. RECLN 110 generates the data signals D[1-M] based upon the provided address input signals A[1-N].

[0106]
FIG. 1E illustrates a synchronous ROM emulator circuit including RECLN circuit 200 as part of a example of FIG. 1D.

[0107] Various preferred embodiments of engine 110 may include either synchronous input circuit 250 and/or synchronous output circuit 240. Synchronous input circuit 250 provides a synchronizing interface capturing address input signals A[1-N]. Synchronous output circuit 240 provides data outputs D[1-M] based upon a synchronization scheme within engine 110 as SD[1-M].

[0108] As used herein a wire refers to a path connecting nodes of a circuit which carries a state between the connected nodes and/or refers to a resonant cavity propagating information in terms of state between the connected nodes. A wire may be made out of metal, an optical chamber, or a tunnel path through a molecular substrate. A wire bundle is a collection of at least one wire.

FIG. 25A illustrates what is referred to by a computer programming language collection 5300.

[0220] As used herein, the computer programming language collection, includes to but is not limited to, procedural languages 5302, functional languages 5304, logic languages 5306, script languages 5308, assembly languages 5310, linkable languages 5312, loadable languages 5314 and event languages 5316. Procedural languages 5302 include but are not limited to FORTRAN, C, C++, Pascal, Java, Modula, and ADA. Functional languages 5304 include but are not limited to LISP and Scheme. Logic languages 5306 include Prolog and constraint based programming languages. Script languages 5308 include but are not limited to HTML, XML and Perl.

[0221] Assembler languages 5310 include but are not limited to assembly languages for actual instruction processors, for abstract instruction processors, for reconfigurable instruction processors, and for virtual instruction processors. As used herein, an actual instruction processor will execute an instruction format for at least one execution entity, which may include but is not limited to a processor engine and/or a datapath. A processor engine may control at least one member of the collection comprising at least one memory component, a messaging element and a finite state machine. Examples of actual instruction processors include but are not limited to microprocessors and digital signal processors.

[0222] Abstract instruction processors are often interpretive instruction processors, supporting an instruction set which is defined independently of a specific instruction processor. Examples of abstract instruction processors include, but are not limited to, the Java byte code abstract machine, the Warner abstract machine used as the intermediate language target of Prolog, the P-code intermediate language used as the compiler target for some implementations of Pascal, and the FORTH language kernel. Note that some of the abstract instruction processors support real-time integration of translated assembly instructions, providing for real-time extensible language environments.

[0223] Assembly languages for reconfigurable instruction processors often possess the ability to define the actions of at least some of the instructions as well as the instruction sequences used to control the execution of reconfigurable instruction processors.

[0224] Virtual instruction processors support virtual computing environments in which instruction actions occur across some communication fabric and involve a virtual real-time environment in which the number and capabilities of the instruction processing elements may vary over time, as well as the responsiveness to instructions and communications may also vary.

[0225] Linkable languages 5312 refer to formats often used as the target format for the assembly process translating assembly language documents. Linkable language documents are designed to be presented to a linkage editor to create at least one loadable language document. Loadable languages 5314 are referred to herein as hexadecimal loader format languages and binary loader format languages. Hexadecimal loader format languages represent addresses and data in a text format as hexadecimal and/or octal representations of data and addresses. A binary loader format language is the most commonly used format for rapid loading of executable documents. Operating systems almost universally support at least one binary loader format language. In many loadable languages, often a sequence of data addresses will be loaded by specifying the starting or ending address, the run length and then the successive data addresses. Many loadable languages additionally support the ability to load documents at varying actual addresses.

[0226] Event languages 5316 include but are not limited to event driven simulation languages such as Verilog and VHDL.

[0227] Some languages may be considered as members of more than one of the collections 5302-5316.
