PURPOSE:To provide a memory device for arithmetic operation capable of shortening operating time, suppressing the man-hour of design, and reducing the capacity of hardware. CONSTITUTION:This device includes a write register 3 which preserves write data transiently, an address register 4 which preserves the address of the write register 3 transiently, and a means 1 which performs the readout operation and write operation of the register simultaneously by using the address of the write register 3 stored in the address register 4 and write data stored in the write register 3, and selects the register, and superimposes the operating time to read out data on that to write the data. |
