Reference is shown as in FIG. 1, which is an architecture block diagram of a silicon storage apparatus according to the prior art. A silicon storage apparatus 1′ comprises a controller 10′, a transmission interface 20′, and at least one storage media interface 30′. The storage media interface 30′ is used to contain and connect with a storage medium 3 and the controller 10′ is used to connect with a processor base system 2 by the transmission interface 20′. Because the controller 10′ has to provide separately enough pins of control signals, such as detecting signals 101′, and data signals 102′ to be used by the storage medium 3, the controller 10′ has to be chosen with larger size to support more functions of the plenty storage media 3. Hence, size of the silicon storage apparatus 1‘can’t be further simplified.
