摘要:
SRAM cells and SRAM cell arrays are described. In one embodiment, an SRAM cell includes a first inverter and a second inverter cross-coupled with the first inverter to form a first data storage node and a complimentary second data storage node for latching a value. The SRAM cell further includes a first pass-gate transistor and a switch transistor. A first source/drain of the first pass-gate transistor is coupled to the first data storage node, and a second source/drain of the first pass-gate transistor is coupled to a first bit line. The first source/drain of the switch transistor is coupled to the gate of the first pass-gate transistor.
