Claim 3:
4. The electronic device of claim 2, wherein the PUF number is a multi-bit number and further wherein:
the memory controller defines the multi-bit number to include a plurality of two-terminal memory devices of the array of two-terminal resistive switching memory including the first two-terminal memory device, the second two-terminal memory device and at least a third two-terminal memory device and a fourth two-terminal memory device;
the memory controller additionally applies the signal at least to the third two-terminal memory device and to the fourth two-terminal memory device in conjunction with the PUF write operation;
the sensing circuit measures at least a third response signal of the third two-terminal memory device compared to the electrical characteristic value and a fourth response signal of the fourth two-terminal memory device compared to the electrical characteristic value; and
the memory controller determines a value of the multi-bit number in response to at least: the comparison of the response signal to the electrical characteristic value, the comparison of the second response signal to the electrical characteristic value, the comparison of the third response signal to the electrical characteristic value and the comparison of the fourth response signal to the electrical characteristic value.
