ABSTRACT:
While a memory section (1) is in standby mode, a power supply/interruption circuit (2) supplies electric power to a memory section (1) only during periods in which a refresh operation is performed in synchronization with a timing of the refresh operation generated by the clock circuit (3), and interrupts power supply to the memory section (1) during periods in which the refresh operation is not performed. Thus, power consumption of the memory section that performs the refresh operations is suppressed, by which a power consumption reduction of the semiconductor storage device is realized.
