Abstract
A semiconductor memory device includes first and second plugs formed on a semiconductor substrate, a word line between the first and second plugs and above the semiconductor substrate, a first semiconductor pillar extending above the semiconductor substrate through the word line, a second semiconductor pillar extending above the semiconductor substrate through the word line, a first bit line electrically connected to the first semiconductor pillar, and a second bit line electrically connected to the second semiconductor pillar. When writing same data in a first memory cell, which is electrically connected to the first bit line, and a second memory cell, which is electrically connected to the second bit line, a first voltage is applied to the first bit line and a second voltage that is different from the first voltage is applied to the second bit line.
