Computer Hardware Terms, Glossary and Dictionary

ROM emulator is a debugging tool that helps debug a ROM chip by simulating the ROM with RAM. Since RAM can be written over, whereas ROM cannot, programming changes can be made easily. ROM emulators link the target system to a host computer. A plug either inserts into the target ROM sockets, clips over SMT ROM chips, or is soldered down in place of the ROM parts. The emulator then links this connection to the host computer over RS-232, Ethernet, or USB.
