Claim 0:
1. A method for operating a circuit, comprising:
grouping a set of resistive switching devices into one or more subsets of resistive switching devices, wherein each subset of the one or more subsets comprises the same number of resistive switching devices;
for each subset of the one or more subsets:
applying a programming cycle to each resistive switching device of that subset;
monitoring that subset for a program event among the resistive switching devices of that subset;
terminating the programming cycle in response to detecting the program event among the resistive switching devices of that subset; and
assigning an associated digital value to that subset based on an identity of a resistive switching device of that subset associated with the program event among the resistive switching devices of that subset; and

constructing a random number from the associated digital values of the one or more subsets of resistive switching devices.
