PROBLEM TO BE SOLVED: To operate a writing and reading memory alternately in one memory operation mode and an interleave multi-memory operation mode by reducing a required space to be occupied by a control element on a chip to the minimum. SOLUTION: A control line 45 connecting a control logic 33 to each memory cell of a cell field 31 is provided, and a selection signal sequence for an interleave multi-memory operation is supplied to the control line 45 when an operation mode signal 46 indicates an interleave multi-memory operation mode, and a mask signal sequence for a writing enable operation is supplied to the control line 45 when the operation mode signal 46 indicates one memory operation mode.
