BANK CONTROLLING CIRCUIT FOR SUPPORTING A PLURALITY OF BANK OPERATIONS AND A SEMICONDUCTOR MEMORY DEVICE USING THE SAME

摘要

PURPOSE: A bank controlling circuit and a semiconductor memory device are provided to reduce an unnecessary current consumption and support a plurality of bank operations by controlling a decoder for transferring a word line signal to the bank selected by a bank address signal.;CONSTITUTION: A switching signal generating unit(20) generates a first switching and a second switching signal with receiving input of a bank address signal. A first decoder(21) generates a word line signal by decoding of a row address signal and outputs to a first bank with response to the first switching signal. A second decoder(22) generates a word line signal by decoding of a row address signal and outputs to a second bank with response to the second switching signal.;COPYRIGHT KIPO 2010
