Abstract
A voltage generator configured to generate a plurality of voltage groups, each of the plurality of voltage groups including a plurality of reference voltages, and a decoder having an output node configured to output one of the plurality of reference voltages is disclosed. The decoder includes switch blocks that correspond to the plurality of voltage groups. Each of the switch blocks includes transistors that are turned on or off by or in response to a control signal, and each transistor in one of the switch blocks has a channel width different from a channel width of each transistor in another one of the switch blocks.
