Abstract:
A one-transistor static random access memory (1T SRAM) device and circuit implementations are disclosed. The 1T SRAM device includes a planar field effect transistor (FET) on the surface of the cell and a vertical PNPN device integrated to one side of the FET. A base of the PNP of the PNPN device is electrically common to the emitter/collector of the FET and a base of the NPN of the PNPN device is electrically common to the channel region of the FET. The anode pin of the PNPN device may be used as a word line or a bit line. A method of forming the 1T SRAM device is also disclosed.
