Abstract

PURPOSE:To reduce the power comsumption of a sense amplifier, by turning off an FET for constant current source by a prescribed control signal during the nonselection of a chip or in the writing mode. CONSTITUTION:In the chip nonselection mode when an external terminal -CS is set at a high level, the control signal R is set at a low level and an MISFETQ32 functioning as a constant currrnt source is turned off. In the chip selection mode when the terminal -CS is set at a low level, the signal R is set at a low level with the Q32 turned off as a long as an external terminal -WE is in the writing mode of a low level. Accordingly the signal R is set at a high level with a sense amplifier SA set in the amplifying mode only in the reading mode when the terminals -CS and -WE are set at a low level and a high level respectively.
