Abstract
A technique relates to a circuit. At least one 4 transistor (4T) static random access memory (SRAM) bitcell is included. Each of the 4T SRAM bitcells includes a first PFET, a first NFET, a second PFET, and a second NFET, the first PFET and the first NFET being coupled to form a first output node, and the second PFET and the second NFET being coupled to form a second output node. A pulldown circuit is coupled to the first NFET, the pulldown circuit operable to pull down a voltage at the first output node. A feedback circuit is operable to monitor the first output node, the feedback circuit operable to control the pulldown circuit.
