Abstract
A system and method for improving a domino SRAM that eliminates the need for additional transistors in series with evaluation transistors. The regular structure inherent in RAM arrays is used to minimize both the effective recharge cycle time and the recharge power required to recharge the various levels of domino SRAM circuits. Using a clock signal as a reference, recharge signals are timed to each other and to other functional signals. By adjusting buffers and wiring delays associated with each recharge signal, the recharge signals sent to each level of logic are delayed until the recharge of the previous level is complete.
