Abstract
Arrangements and methods for a program-read-erase memory using ReRAM cells is disclosed. The memory includes an array of pristine ReRAM cells. A first digital symbol is encoded in the memory by partially forming cells, while the opposite digital value is encoded in pristine cells. As part of a read process, all cells are subject to partial formation voltage which erases all data as it is being read. ReRAM memories used in this manner are advantageously usable to store challenges for interrogating PUFs for recovery of PUF-generated encryption keys.
