Microcomputer with severable ROM |
摘要 |
A microcomputer has provision for both on-chip ROM (on the same chip as the CPU) and off-chip ROM and which may operate with only on-chip ROM as only off-chip ROM has the hardware capability to disable on-chip ROM permanently, so that chips having defective ROM may be salvaged by being converted to computer chips that use only off-chip ROM.
