Classification: CPC G | IPC G

Claim 14:
15. A method for operating a circuit, comprising:
grouping a set of resistive switching devices into a plurality of pairs of resistive switching devices;
for each pair of the plurality of pairs:
applying a programming cycle to each resistive switching device of that pair;
monitoring that pair for a first program event among the resistive switching devices of that pair;
terminating the programming cycle in response to detecting the first program event among the resistive switching devices of that pair; and
assigning an associated digital value to that pair based on an identity of a resistive switching device of that pair associated with the first program event among the resistive switching devices of that pair;

constructing a random number from the associated digital values of the plurality of pairs of resistive switching devices;
programming each resistive switching device of the set of resistive switching devices; and
erasing each resistive switching device of the set of resistive switching devices.
