A semiconductor integrated circuit device includes an address buffer which receives
an address signal that indicates an address of a memory cell array, a latch circuit
which latches the data, and an address transition detection circuit which detects
transition of the address. During the access operation of the memory cell array,
an address at the operation start time is latched by the latch circuit. After the
end of the operation of the memory cell array, an address that is currently input
to the address buffer is latched by the latch circuit. If the received address
signal is data different from the latch data, a control signal that controls the
cycle operation of the memory cell array for a predetermined period is generated
on the basis of the detection result from the address transition detection circuit.
