Abstract
The invention provides an apparatus and method for reducing the access time of a memory cell after a write operation. A one-shot generation circuit generates a one-shot pulse in response to a falling edge on an external write line or a change in the state of the data signal during an inactive state of the write signal. This one-shot pulse then controls writing data into a static memory cell. Since it is not necessary to wait for the write external line to go high before triggering the end of the internal write pulse, the access time of the static memory device is reduced.
