Abstract
An integrated circuit with SRAM cells containing dual passgate transistors and a read buffer, all connected to one word line is disclosed. The read buffer and one passgate transistor may be variously configured to a separate read data line and write data line, or a combined data line, in different embodiments. The read buffer in addressed SRAM cells may be biased during read operations. The read buffer in half-addressed SRAM cells may be biased or floated, depending on the configuration of the read data line and the write data line. The read buffer in addressed and half-addressed SRAM cells may be biased or floated, depending on the configuration of the read data line and the write data line.
