Abstract

Dynamic latches for writing to a synchronous RAM are controlled by a clock signal and a delay circuit so that the dynamic latches will not stay in a latched state for more than a selected time interval regardless of the clock signal. One delay circuit limits the length of a write enable signal. Another delay circuit responds to the write enable signal and after a delay returns the address and data latches to their transparent states.
