Abstract
An SRAM memory cell structure utilizing a read driver transistor and a column select write transistor, and a method of operating the same. The SRAM memory cell comprises first and second cross-coupled inverters, having a first and second latch nodes, respectively. The cell further comprises a first write pass transistor connected between the first latch node of the first inverter and a first pass node, and a first wordline pass transistor connected between the first pass node and a first bitline. The cell also includes a first read driver connected between the first pass node and a source potential, and a control terminal of the first read driver connected to the second latch node of the second inverter.
