ABSTRACT:
A peripheral voltage generator is provided for reducing an operating current by generating a peripheral voltage within a mobile SDRAM, and a current is used in a deep-power down mode and a self refresh mode to thereby enhance operational characteristics. The peripheral voltage generator includes a reference voltage generating unit for generating a peripheral reference voltage having a different level in response to an enable signal and a self-refresh signal; a comparing unit for comparing the peripheral reference voltage with a peripheral driving voltage to thereby output a peripheral voltage control signal based on the comparison result; and a peripheral voltage control unit for generating the peripheral driving voltage having a first peripheral level in response to the peripheral voltage control signal.
