Abstract

An SRAM cell includes a first inverter cross-coupled to a second inverter. The first inverter includes a first pull-up transistor and a first pull-down transistor, having coupled drains that define a first storage node. The SRAM cell further includes a first N-type pass-gate transistor having a first drain coupled to a write bit line, a first source coupled to the first storage node, and a first gate coupled to a first write word line. The SRAM cell further includes a first P-type pass-gate transistor having a second drain coupled to the write bit line and a second source coupled to the first storage node. The SRAM cell further includes a P-type transistor having a third drain, coupled to a second gate of the first P-type pass-gate transistor, a third source coupled to a second write word line, and a third gate coupled to an enable signal.
