A static memory circuit which can stably conduct a write operation with large margins is disclosed. The memory circuit comprises a plurality of static type memory cells, a first terminal for receiving input data to be written, a second terminal for receiving a control signal for changing an operation mode of the memory from a read operation mode to a write operation mode, a latch circuit for holding the input data during the write operation mode, and circuitry for applying the held data by the latch circuit to a selected memory cell.
