PROBLEM TO BE SOLVED: To provide a memory control circuit, which increases access speed to a memory and suppresses increase of a mounting area. SOLUTION: The memory control circuit includes: a serial data processing circuit which performs serial access, receives first access data for accessing a parallel-access memory by using a terminal used for serial access, and which serially outputs first access data; a parallel data processing circuit to receive second access data and outputs the second access data in parallel; and a selection circuit which, if a first instruction signal for instructing serial access is input, outputs the first access data from the serial data processing circuit in serial to a serial-access memory, and if a second instruction signal for instructing parallel access is input, outputs the second access data from the parallel data processing circuit in parallel to a parallel-access memory.
