a The photo of fabricated 40 nm ReRAM chip. There are several ReRAM modules on a single chip that could build up a ReRAM tile. b The microscopic photo of one ReRAM module. The array size of one typical ReRAM module is 128 × 128. The ReRAM module can be configured for the PUF/TRNG/CIM function. c The closed-loop system in this work. The system consists of the ReRAM chip, the AMD VC707 FPGA, the printed circuit board (PCB), and an Aardvark I2C/SPI adapter. The adapter further connects to the personal computer (PC). FPGA: Field Programmable Gate Array. SPI: Serial Peripheral Interface. BL: bit-line. WL: word-line. ADC: analog-to-digital converter. d The schematic of one ReRAM-based CIM module in this system.
