Patent ID: 7706174

Claim:
A static random access memory comprising: a. a first inverter having a supply voltage node connected to a supply voltage, and a ground node connected to ground; b. a second inverter cross-coupled with the first inverter and having a supply voltage node connected to a supply voltage, and a ground node; and c. a switch for selectively connecting and disconnecting the ground node of the second inverter to and from ground; and wherein each inverter has a Q node and a QB node, and the memory further comprises: d. a bit-line; e. a write switch for selectively connecting the bit line to the Q nodes of the inverters during a write operation; and f. a pair of read switches connected in series between the bit line and ground, the read switches comprising: i. a first read switch controlled by a read signal; and ii. a second read switch controlled by the voltage at the QB nodes of the inverters.
