-## Please fill in your project documentation in this README.md file
+This project contains array of various sizes of 1T1R devices and a 1T1R 256x256 ReRAM module for device performance characterization, e.g. I-V, transient, R-ratio, and variations, and ReRAM simulation model verification. The goal is to design a low power ReRAM controller optimized for write/read latency, endurance, and power consumption based on the actual measurement results of sky130 ReRAM devices.
:warning: | Use this sample project for analog user projects.
