MEMORY DEVICE AND METHOD FOR PRECHARGING MEMORY DEVICE

摘要

A memory device and a method for precharging the memory device are provided to increase integration density as enabling high speed operation, by precharging an input stage of a sense amplifier using a plurality of precharge parts and multiplexers. A signal transmission apparatus includes signal line pairs, precharge elements(610,620,630), a sense amplifier(650) and a multiplexer(640). The precharge parts precharge the signal line pairs. The multiplexer connects one signal line pair to the sense amplifier during signal transmission period, and connects more than two signal line pairs to the sense amplifier during preparation period.
