Abstract:
A non-volatile static random access memory cell and includes a bistable regenerative circuit coupled to first and second transistors and to first and second non-volatile memory cells. Methods of use include directly transferring a complementary data bit between the non-volatile memory cell and the bistable regenerative circuit. Alternatively, complementary data from the bistable regenerative circuit may be regenerated by a sense amplifier and a second bistable regenerative circuit before being transferred to non-volatile memory cells in a column of memory cells. The bistable regenerative circuit may be reset to ground potential. Applications using the non-volatile SRAM cell with direct read out from the bistable regenerative circuit include a non-volatile flip-flop or non-volatile multiplexer.
