摘要:
An 8-transistor SRAM cell which includes two pull-up transistors and two pull-down transistors in cross-coupled inverter configuration to form two inverters for storing a single data bit, wherein each of the inverters includes a Schottky diode; first and second pass gate transistors having a gate terminal coupled to a write word line and a source or drain of each of the pass gate transistors coupled to a write bit line; and first and second read transistors coupled to the two pull-up and two pull-down transistors, one of the read transistors having a gate terminal coupled to a read word line and a source or a drain coupled to a read bit line. In a preferred embodiment, the 8-transistor SRAM cell has column select writing enabled for writing a value to the 8-transistor SRAM cell without inadvertently also writing a value to another 8-transistor SRAM cell.
