Abstract:
A memory cell including a cross-coupled latch with corresponding storage nodes, and further including first and second write pass gate transistors and first and second read pass gate transistors. The write pass gate transistors are controlled by a write word line and the read pass transistors are controlled by a read word line. Each read and write pass gate transistor is coupled between a storage node and either a bit line or a complementary bit line. The write pass gate transistors are implemented at a first strength level and the read pass gate transistors are implemented at a second strength level which is less than the first strength level. In this manner, the read and write margins are independently configurable without negatively impacting each other.
