Abstract
A microcomputer includes an instruction execution unit and an internal memory formed on the same chip. A first circuit is provided for setting a memory access cycle for a read/write to the internal memory shorter than that for read/write to an external memory. Further, a second circuit is provided for setting the memory access cycle for the read/write to the internal memory substantially equal to that for the read/write to the external memory. The first and second setting circuits are alternatively and selectively activated.
