PURPOSE: A triple port device of a semiconductor memory device is provided to increase operation process capacity of a microprocessor by processing the command including three operands. CONSTITUTION: A first operand processor(510) is driven with an inversed third clock and a first port enable signal. A second operand processor(520) is driven with an inversed fourth clock and a second port enable signal. A third operand processor(530) is driven with an inversed fifth clock and a third port enable signal. |
