Abstract:
A memory cell comprises a pair of cross-coupled inverters as a storage element, a first inverter in the pair of cross-coupled inverters having a first output at a first node, a second inverter in the pair of cross-coupled inverters having a second output at a second node. A first complementary transmission gate includes a first nMOS pass gate and a first pMOS pass gate, connected between the first node and a first bit line. A second complementary transmission gate includes a second nMOS pass gate and a second pMOS pass gate, connected between the second node and a second bit line. A first word line is connected to gate conductors of the first and second nMOS pass gates in the first and second complementary transmission gates. A second word line is connected to gate conductors of the first and second pMOS pass gates in the first and second transmission gates.
