Abstract
A semiconductor memory device includes a first first-type well including a first cell array for storing a data to apply the data to one of a first bit line and a first bit line bar, and a first precharge MOS transistor having a second-type channel for equalizing voltage levels of the first bit line and the first bit line bar; a first second-type well including a first sense amplifying MOS transistor having a first-type channel for sensing and amplifying the signal difference between the first bit line and the first bit line bar, and a first connection MOS transistor; and a second first-type well including a second sense amplifying MOS transistor having a second-type channel for sensing and amplifying the signal difference between the first bit line and the first bit line bar.
