NOR flash replacement
While flash memory remains one of the most popular storages in embedded systems because of its non-volatility, shock-resistance, small size, and low energy consumption. Its application has grown much beyond its original design: NOR flash memory is designed to store binary code of programs because it supports XIP (eXecute-In-Place) and high performance in read operations, while NAND flash memory is used as a data storage because of its lower price and higher performance in write/erase operations, compared to NOR flash.
