Abstract:
Magneto-resistive random access memory (MRAM) employing an integrated physically unclonable function (PUF) memory. The MRAM includes an MRAM array comprising an MRAM data array of data MRAM bit cells and an MRAM PUF array comprising PUF MRAM bit cells to form an integrated MRAM PUF array in the MRAM array. A resistance sensed from the PUF MRAM bit cells is compared to a reference resistance between the reference MRAM bit cells in the accessed MRAM bit cell row circuit in response to a read operation to cancel or mitigate the effect of process variations on MRAM bit cell resistance. The difference in sensed resistance and reference resistance is used to generate a random PUF output. By integrating the MRAM PUF array into an MRAM array containing an MRAM data array, access circuitry can be shared to control access to the MRAM data array and MRAM PUF, thus saving memory area.
