ABSTRACT:
A static random access memory (SRAM) cell includes a SRAM circuit and a programmable resistor connected to a storage node of the SRAM circuit. The SRAM circuit can be any type of SRAM circuit, such as a 3T, negative differential resistance (NDR) transistor-based circuit, or a 6T (conventional SRAM) circuit. The programmable resistor can be formed in a metal layer above the SRAM circuit to minimize the area requirements for the memory cell. Just before shutdown of the SRAM cell, the resistance state of the programmable resistor is changed (if necessary) based on the data value stored at the storage node. The programmable resistor provides a non-volatile indication of the stored data value at the time of power off. Then, when power is restored to the SRAM cell, a data value based on the resistance state of the programmable resistor is written back into the SRAM circuit.
