| abstract |
A semiconductor storage device includes word lines extending in first and second directions, and separated from each other in a third direction, sense amplifier circuits that partially overlap the word lines in the third direction, memory strings intersecting the word lines and extending in the third direction, memory-side bit lines extending in the first direction, separated from each other in the second direction, and including first and second adjacent memory-side bit lines, circuit-side bit lines between the word lines and the sense amplifier circuits and partially overlapping the respective memory-side bit lines in the third direction, and contact plugs extending in the third direction and respectively connecting the memory-side bit lines and the circuit-side bit lines. The contact plugs include first and second contract plugs that are electrically connected to the first and second memory-side bit lines, respectively, and are not aligned along the first or second direction. |
