MEMORY CIRCUIT HAVING NON-VOLATILE MEMORY CELL AND METHODS OF USING

Abstract:

One aspect relates to a memory circuit that has a programmable non-volatile memory (NVM) cell configured to generate an NVM output signal indicative of a program state of the NVM cell and to configure a volatile output based on the program state of the NVM cell. The NVM cell comprises a first magnetic tunnel junction (MTJ) device, a first select device connected in series with the first MTJ device at a first node, and a first pass device. The memory circuit also may have a programmable (independently of the NVM cell) volatile memory (VM) cell configured to receive the NVM output signal at a VM input node and to generate a VM output signal indicative of the program state of the VM cell.
