Abstract:
A semiconductor memory device includes wirings arranged in parallel along a first direction, the wirings including first and second wirings that are adjacent and a third wiring adjacent to the second wiring, a first pillar between the first and second wirings and a second pillar between the second and third wirings, the first and second pillars each extending in a second direction crossing the first direction toward the semiconductor substrate, and first and second bit lines connected to the first and second pillars, respectively. A first voltage is applied to the second wiring during a program operation on a first memory cell at an intersection of the second wiring and the first pillar, and a second voltage higher than the first voltage is applied to the second wiring during a program operation on a second memory cell at an intersection of the second wiring and the second pillar.
