Abstract
A single chip microcomputer includes a multiport memory, such as a dual-port memory, having a data selector by which, when addresses which are input to first and second ports of the dual port memory are in agreement and the first and second ports are respectively set in a write mode and a read mode, write data supplied to the first port is directly transmitted as read data from the second port. The microcomputer also has an arithmetic logic unit which supplies the write data to the multiport memory and supplies the write data to selected memory cells in accordance with the selection being effected via an address decoder corresponding to the first port.
