Claims
- 1. A method of detecting a short from a digit line to a cell plate, comprising:
- charging said digit line to a first potential, wherein said first potential represents a logic value;
- charging a complementary digit line to a second potential representing a complementary logic value;
- allowing said short to urge said digit line to a third potential;
- providing electrical communication between said digit line and said complementary digit line;
- allowing said digit line and said complementary digit line to establish an initial common voltage generally between said second potential and said third potential;
- equilibrating said digit line and said complementary digit line toward a final common voltage generally between said first potential and said second potential, wherein said equilibrating occurs at an equilibration rate; and
- limiting said equilibration rate.
- 2. The method in claim 1, wherein charging a digit line further comprises writing said logic value to a cell.
- 3. The method in claim 2, further comprising receiving a first signal, and wherein allowing said short to urge said digit line to a third potential is performed in response to receiving said first signal.
- 4. The method in claim 3, further comprising receiving a second signal, and wherein providing electrical communication is performed in response to receiving said second signal.
- 5. The method in claim 3, wherein:
- said first signal has a first voltage level;
- said second signal has a second voltage level; and
- said second voltage level is higher than said first voltage level.
- 6. The method in claim 5, wherein:
- said first signal has a test duration and a non-test duration; and
- said test duration is longer than said non-test duration.
- 7. The method in claim 6, wherein said first signal and said second signal are RAS signals.
