ABSTRACT:
A single-chip microcomputer includes therein an electrically programmable read-only memory (EPROM) including a specific cell of the EPROM storing an item of information for discrimination of memory space. When a reset signal is applied for initializing the single-chip microcomputer, the specific cell of the EPROM is selected and read out, and further latched in a latch circuit. On the basis of the content of the latch circuit, the single-chip microcomputer discriminates and sets a boundary between an internal memory and an external memory during programmed operation.
