Classification: CPC nan | IPC G  H

Claim 0:
1. A method, comprising:
initiate a physical unclonable feature (PUF) write process for generating identifier data at a resistive switching memory array;
determine a number, X, of bits for the PUF write and first addresses within the resistive switching memory array corresponding to a plurality of resistive switching memory cells targeted for the PUF write;
identify a number, P, of correction bits required for the X bits of identifier data;
allocate X+P bits of resistive memory for the X bits of identifier data plus the correction bits;
allocate X differential bits at second addresses in the resistive memory for differential cell generation of the identifier data;
electrically couple bitlines of respective pairs of bits from the first addresses and the second addresses, wherein each pair of bits comprises one resistive memory cell from the first addresses and one resistive memory cell from the second addresses;
initiate a forming pulse for the PUF write at each pair of bits at the first addresses and the second addresses;
complete the forming pulse in response to a termination condition;
read a data pattern generated in the X bits of identifier data at the first addresses in response to the forming pulse;
generate correction data for the data pattern; and
save the correction data to the P bits of the resistive memory allocated for the correction bits.
