PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device which can reduce the power consumption while eliminating the limits on address inputting, and to provide its access method. SOLUTION: This integrated circuit has address buffers 1 and 2 to input the address signals ADx, ADy instructing the address of the memory cell array 19, latch circuits 3-6 to latch these data, address transition detector circuits 7, 8 detecting the transition of the address. It latches the address at the time to start the above operations during accessing the memory cell array, and at the time after the end of the operation of the memory cell array, takes the address inputted in the address buffer into the latch circuit, and if those data are different from the latch data, generates the control signal CYCLE which controls the cycles operation of the memory cell array for the predetermined period according to the result of the address transition detection circuit.
