Classification: CPC G | IPC G

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

constructing an additional random number from the associated digital values of the additional plurality of pairs of resistive switching devices.
