Title: Semiconductor memory
Inventor: SHINOZAKI NAOHARU
IPC: G11C11/403
Filed: 2003-01-29
Abstract: PURPOSE: To reduce power consumption in a power saving mode in a semiconductor memory having a memory cell requiring a refresh operation. CONSTITUTION: A partial area for holding data in the power saving mode is composed of one of a plurality of memory cells connected to a bit line. An operation controller operates a memory cell selected in accordance with an address signal in a normal operation mode for performing a read operation and a write operation. The operation controller continuously latches the data held in the memory cell of the partial area on a sensor amplifier in the power saving mode. This eliminates the need for a refresh operation that holds the data of the memory cell in the power saving mode. Because the data can be held without performing a refresh operation, power consumption in the power saving mode can be reduced.
