ABSTRACT:
A microcomputer system comprises a microprocessor and a memory chip which has on a single semiconductor substrate a pointer for indicating an address of an instruction code fetch destination, an incrementer for incrementing the pointer and a memory for storing programs and data. The microprocessor controls the update timing of the pointer in the memory chip, so that the instruction codes can be continuously read from the memory of the memory chip without outputting the addresses of the instruction code fetch destination from the microprocessor.
