Abstract
A microcomputer with a stored program memory has a detecting circuit for detecting a memory access error by which an unrequired code is read out of the memory. The detecting circuit receives a read-out instruction code from the memory according to memory access operation in parallel with a receiving operation of an instruction decoder and detects a read-out code from a memory location in which a program to be processed is not written. Undesired processing can be immediately inhibited and the operator can easily find the occurrence of the memory access error.
