Abstract
In a dynamic RAM, the refreshing operation is performed during one cycle of the read or write operation. A switch circuit selects either a row address signal output from address input circuit or a refresh row address signal output from a refresh circuit. By controlling the switch circuit by a switch selector, the refresh is performed during the operation delay time of the address input circuit or an input/output circuit for inputting and outputting data.
