INTERNAL VOLTAGE GENERATING CIRCUIT INCLUDING AN INTERNAL VOLTAGE GENERATING UNIT AND A SEMICONDUCTOR MEMORY DEVICE

摘要

PURPOSE: An internal voltage generating circuit and a semiconductor memory device are provided to drive an internal voltage by securing sufficient driving power in a read or write operation.;CONSTITUTION: A first internal voltage generating unit(1) generates an internal voltage in an active operation. A second internal voltage generating unit(2) generates the internal voltage when the active operation is performed and an operation of a column path for a read operation or a write operation is started. A distribution voltage generating unit generates a distribution voltage by distributing the internal voltage. A comparison signal generating unit generates a comparison signal by comparing a distribution voltage with a reference voltage in response to an active signal enabled in an active operation.;COPYRIGHT KIPO 2012
