ABSTRACT:
An SRAM cell that is accessed by a single word line and separate access transistors for read and write operations. A pair of write bit line transfer devices provide respectively access to the right and left sides of cross coupled pull-up, pull-down transistor pairs for a write operation, and a single read bit line transistor in series with the word line transistor, when selected, reads the content of the cell.
