Abstract
A computer memory system provides self-timed precharging and output signal latching. The method and apparatus are useful in accelerating search cycles for associative data in a memory such as a content addressable memory (CAM) where single transition memory search and output signal encoding is required. Feedback is provided to initiate memory precharging as soon as an actual search of the memory ends rather than at a next system clock transition.
