Circuit for memory write data operation
Abstract:
A pulsed dynamic LCV circuit for improving write operations for SRAM. The pulsed dynamic LCV circuit includes voltage adjustment circuitry having a plurality of selectable reduced supply voltages and timing adjustment circuitry having a plurality of selectable logical state transition timings for adjustably controlling the voltage and timing of a transition from a selected reduced supply voltage back to a nominal supply voltage. The voltage adjustment circuitry has a plurality of selectable transistors that when individually selected have a cumulative effect to pull the reduced supply voltage down further. The timing adjustment circuitry has a plurality of selectable multiplexers that when individually selected for a delayed voltage transition have a cumulative effect to delay return of voltage supplied to SRAM from a reduced supply voltage to a nominal supply voltage.
