SEMICONDUCTOR MEMORY DEVICE HAVING INNER POWER CIRCUIT FOR CONTROLLING VOLTAGE

摘要

PURPOSE: A semiconductor memory device having an inner power circuit for controlling a voltage is provided to control a size of an inner power voltage by using a control signal. CONSTITUTION: A semiconductor memory device having an inner power circuit for controlling a voltage comprises a reference voltage controller and generator(311), an inner power reference voltage generator(321), and an inner power voltage generator(331). The reference voltage controller and generator inputs an outer power voltage and a control signal, generates a reference voltage, and varies a level of the reference voltage according to the voltage level of the control signal. The inner power reference voltage generator generates a reference voltage for an inner power. The inner power voltage generator generates an inner power voltage.
