ABSTRACT:
A memory array divided into a plurality of sub-memory-arrays is disposed on a chip so that, if a specified sub-memory-array is selected by a sub-memory-array selecting circuit, a normal read/write operation is performed with respect to the sub-memory-array based on an address indicated by a group of external address signals. At the same time, a clock generator for self-refresh mounted on a chip generates a word-line basic clock for self-refresh and a word-line basic clock for refresh, thereby selecting the word lines in the sub-memory-arrays which have not been selected. Prior to a predetermined time at which the sub-memory-array subjected to a refresh operation is subsequently selected, a refresh halt signal is outputted so as to forcibly halt the refresh operation, thereby preventing insufficient recharging of a memory cell. Each of the plurality of sub-memory-arrays stores, of sequential sets of image data, data on one frame or one field.
