Tracking pulse generator and RAM with tracking precharge pulse generator

摘要

A memory has at least one decoder responsive to a synchronizing pulse for providing a selection signal to the memory cells coincident with the partial selection signal for thereby selecting a group of memory cells for an operation. The decoder has a variable time delay characteristic between the synchronizing pulse and the selection signal. The pulse generator has a mimicking circuit responsive to the synchronizing pulse for providing the partial selection signal to the group of memory cells. The mimicking circuit provides a time delay characteristic between the receipt of the synchronizing pulse and the partial selection signal which mimics the variable delay characteristic of the at least one decoder.
