Semiconductor memory device having low power consumption type column decoder and read operation method thereof
Abstract:
The present invention relates to a semiconductor memory device having a low power consumption type column decoder and read operation method thereof. In accordance with the semiconductor memory device and read operation method thereof according to the present invention, one of a plurality of decoding units of a column decoder is selectively operated according to a logic value(s) of one of some of bits of a column address signal. It is thus possible to reduce unnecessary switching current.
Abstract(Chinese):

本发明涉及具有低功耗型列解码器及其读取操作方法的半导体存储器件。 根据本发明的半导体存储器件及其读取操作方法，列解码器的多个解码单元之一根据列地址的一些位的逻辑值选择性地操作 信号。 因此可以减少不必要的开关电流。
