Abstract
A semiconductor storage device includes first and second chips and first and second power supply electrodes. The first chip includes conductive layers arranged in a first direction, a semiconductor pillar extending in the first direction and facing the conductive layers, first contacts extending in the first direction and connected to the conductive layers, second contacts extending in the first direction and connected to a first power supply electrode, third contacts extending in the first direction, facing the second contacts in a direction crossing the first direction, and connected to the second power supply electrode, and first bonding electrodes connected to the first contacts. The second chip includes a semiconductor substrate, transistors provided on the semiconductor substrate, fourth contacts connected to the transistors, and second bonding electrodes connected to the fourth contacts. The first and second chips are bonded together so that respective first and second bonding electrodes are connected together.
