DEVICE AND METHOD FOR CONTROLLING A NUMBER OF ENABLED-DRIVERS

摘要

A semiconductor device capable of controlling the number of enabled drivers and a method thereof are provided to control the number of drivers enabled according to the variation of operation frequency or surrounding temperature of the semiconductor device. A detection signal generator(11) generates a detection signal by detecting operation frequency of a semiconductor device. A plurality of drivers(15) supplies a corresponding internal voltage to a memory cell array in response to an enable signal. At least one transmission control circuit(13) controls to transmit the enable signal to at least one driver of the plurality of drivers in response to the detection signal.
