A multi-block SRAM memory system is described where a single global clock pulse is distributed to each memory block from the central control. At each SRAM memory block a local signal generator uses the globally distributed clock pulse to generate the required memory control pulse signals. By generating the memory control pulses locally, instead of distributing these from the central control the variations in skew are greatly reduced. Thus the required timing relationship between memory control signals can be achieved with smaller timing margins. This allows higher speed memory cycle and more reliable memory operation.
