Abstract
A self-timed precharge circuit for a memory array consisting of an X-line complement circuit connected to the outputs of a plurality of falling edge detectors, and a precharge generator circuit connected to the output of the X-line complement circuit. Each falling edge detector is connected to a separate wordline (WL, WL+1, . . . WL+N) of the system memory array. In operation, the precharge generator circuit is triggered with a signal on the output lead from a falling edge detector which is activated when the selected wordline (WL, WL+1, . . . WL+N) connected thereto resets.
