Abstract
A device may include, but is not limited to, a bit line; a power line supplied with a power voltage; a sense amplifier circuit amplifying a voltage of the bit line by using the power voltage of the power line; and a control circuit configured to respond to an active command and supply, as the power voltage, the power line with a first voltage during a first period and a second voltage lower than the first voltage during a second period. The control circuit is further configured to respond to a refresh command and supply, as the power voltage, the power line with the second voltage during both the first and second periods.
