ABSTRACT:
A number of control signals for accessing a random access memory may be generated using a cascade connection of data latches. A control signal generator produces two non-overlapping timing signals and their complements from a single input clock signal. The non-overlapping signals of each type are connected to alternate ones of the data latches in the cascade chain. The input to the data latch chain receives the memory access pulse which is then used to derive the various control signals for the random access memory. A plurality of flip-flops have their set and reset terminals connected to the output terminals of various ones of the data latches to produce output control signals from each flip-flop. These control signals have the desired timing relationship to the access pulse.
