A Flash Emulator is used in place of an Flash memory in an embedded circuit. It is fabricated from static RAM devices to emulate the Flash and allows code to be downloaded from a host PC into RAM and made available to the target as if it were stored in the Flash.
Using an Flash Emulator is a useful way of modifying parameters held in the emulator without the hassle of having to reprogram a real Flash Device and plug it into the target circuit board.
