Abstract
PURPOSE:To simplify refresh operation by executing the refresh operation by trailing a read write instruction signal in a standby state in which both the inverse of RAS and the inverse of CAS are High. CONSTITUTION:In the standby state, in which both the signal (the inverse of RAS) strobing a row address, and the signal (the inverse of CAS) strobing a column address, are high, the signal, the inverse of W instructing the read write comes to a low level from the High level, a transistor (TR) 1 turns off, and after delay time generated in an integration circuit 4 elapses, the TR 2 turns on. Accordingly, an internal counter signal is inputted, and an internal counter is generated, and that spot is refreshed. Thus, by only setting the time when the read write instruction signal, the inverse of W trails, the refresh operation can be executed, and time setting in the case of a system design becomes simple.
