Abstract
A semiconductor memory device includes first and second chips. The first chip includes a first region and a second region. The first region includes memory cells, bit lines, word lines, and first bonding electrodes electrically connected to bit lines. The second region includes contacts electrically connected to word lines and second bonding electrodes electrically connected to contacts. The first bonding electrodes include a third bonding electrode and a fourth bonding electrode adjacent. The second bonding electrodes include a fifth bonding electrode and a sixth bonding electrode adjacent. A distance from a center position of the third bonding electrode to a center position of the fourth bonding electrode and a distance from a center position of the fifth bonding electrode to a center position of the sixth bonding electrode are matched in a range of from 90% to 110%.
