Abstract
PURPOSE:To use an input terminal in time division and to reduce the number of terminals by holding inputted address and data signals in respective latch circuits at the leading edge and trailing edge of a clock pulse. CONSTITUTION:In case of executing writing processing in a memory, characteristic data stored in a memory 2 of a memory cartridge 1 is read out at first. Then, a read/write signal R/W and a clock pulse phi are set to L levels. Since the address and data signals use terminals 13, 3C in common, the address signal is prevented from being sent to a data bus. At this time, the clock signal phiis raised and the address signal sent from a CPU 11 is latched by an address latch circuit 4 through the terminals 13, 3C. After a fixed time, data to be written in the memory 2 is outputted to a data bus, the clock pulse phi is decayed and latched by a data latch circuit 5 and written in the memory 2 on the basis of the address.
