Abstract

A semiconductor memory device includes a first chip, a second chip, and a multiple of bonding pads. The first chip has a multiple of memory pillars that penetrate a multiple of wiring layers in a first direction. The second chip is bonded to the first chip. The multiple of bonding pads are provided at a bonding face between the first chip and the second chip. The multiple of bonding pads include a first bonding pad that electrically connects a first memory pillar among the multiple of memory pillars to one of a multiple of transistors, and a second bonding pad that neighbors the first bonding pad when seen from the first direction, and which electrically connects a second memory pillar among the multiple of memory pillars to one of the multiple of transistors. The second memory pillar does not neighbor the first memory pillar when seen from the first direction.
