F021 Level 2 Flash Module Controller (L2FMC)

The Flash electrically erasable programmable read-only memory module is a type of nonvolatile memory

that has fast read access times and is able to be reprogrammed in the field or in the application. It also

allows remapping of the flash to RAM spaces in order to save on repeated program/erase cycles. This

chapter describes the Level 2 F021 Flash module controller (L2FMC).
