Write state machine architecture for flash memory internal instructions

摘要

A system and method for a write state machine for a non-volatile memory. The write state machine has an associated read only memory (ROM) for storing instructions for operation of the non-volatile memory. The ROM is coupled to an input of a write state machine. An instruction needed to perform an algorithm is stored as a micro-instruction in the ROM such that an instruction sequence is changed by only reprogramming the ROM.
