Abstract
An external clock signal is transmitted as a clock signal to a memory core through a first signal transmitting path. In response to activation of the clock signal CLK, memory core starts a read operation. Read data output from memory core is latched by a latch circuit. An external signal designating a latch timing is transmitted as a latch timing signal to the latch circuit through a second signal transmitting path. A delay circuit is provided in at least one of the first and second signal transmitting paths, so that the first and second signal transmitting paths come to have the same signal delay.
