Abstract: An internal voltage generator when activated, generates an internal voltage to be supplied to an internal circuit. Operating the internal voltage generator consumes a predetermined amount of the power. In response to a control signal from the exterior, an entry circuit inactivates the internal voltage generator. When the internal voltage generator is inactivated, the internal voltage is not generated, thereby reducing the power consumption. By the control signal from the exterior, therefore, a chip can easily enter a low power consumption mode. The internal voltage generator is exemplified by a booster for generating the boost voltage of a word line connected with memory cells, a substrate voltage generator for generating a substrate voltage, or a precharging voltage generator for generating the precharging voltage of bit lines to be connected with the memory cells.

Abstract: A precharge voltage generating circuit outputs any of a plurality of kinds of precharge voltages in accordance with an ambient temperature. A precharge circuit supplies the precharge voltage to a bit line during the nonaccess of a dynamic memory cell. A sense amplifier amplifies a difference between the voltage of a data signal read from the dynamic memory cell onto the bit line and the supplied precharge voltage. The precharge voltage is altered in accordance with the ambient temperature, whereby the read margin of the sense amplifier can be changed, and the worst value of the data retaining time of the memory cell can be improved. As a result, the frequency of refreshing of the memory cell can be lowered, reducing power consumption and a standby current.
