Claim 2:
3. The method of claim 2, further comprising, after erasing each resistive switching device:
grouping the set of resistive switching devices into an additional one or more subsets of resistive switching devices;
for each subset of the additional one or more subsets:
applying an additional programming cycle to each resistive switching device of that subset;
monitoring that subset for an additional program event among the resistive switching devices of that subset;
terminating the additional programming cycle in response to detecting the additional program event among the resistive switching devices of that subset; and
assigning an additional associated digital value to that subset based on an identity of a resistive switching device of that subset associated with the additional program event among the resistive switching devices of that subset; and

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