Abstract
A static Random Access Memory (RAM) has a sense enable circuit. A user-determinable number of timing cells produces a timing bit line output in response to a wordline enable input. A sense timing control circuit is triggered by the timing bit line output. The sense timing control circuit produces a sense enable signal for enabling a sensing amplifier to read the logic state of memory cells in communication with the sensing amplifier. A user can change the number of timing cells to optimize operation.
