An Ultracompact Switching-Voltage-Based Fully Reconfigurable RRAM PUF With Low Native Instability

In this brief, an ultracompact and highly reliable physical unclonable function (PUF) is presented based on the mainstream resistive random access memory (RRAM) devices. With the entropy originating from the switching voltage between the high-resistance state (HRS) and the low-resistance state (LRS), the proposed RRAM PUF can be generated during the RRAM’s standard SET operation, leading to minimi...
