Abstract:
A write masked latch bit cell of an SRAM includes a write mask circuit that is responsive to assertion of a first write mask signal to cause a value of a write data node to be a first value and is responsive to assertion of a second write mask signal to cause the value of the write data node to have a second value. A pass gate supplies the data on the write data node to an internal node of the bit cell responsive to write word line signals being asserted. A keeper circuit maintains the value of the first node independently of values of the write word line signals while the first write mask signal and the second write mask signal are deasserted.
