Abstract
A semiconductor device includes a cell array region, a contact region, a gate stack structure, a channel structure extending through the gate stack structurem, and gate contact portions connected to respective gate electrodes. At least some of the gate contact portions extend through a through gate electrode to a connection gate electrode. The gate contact portions include contact groups extending from a first side to a second side of the gate electrodes. Each of the electrode groups includes an upper group on a lower group. Each of the contact groups includes a first group connected to the upper group and a second group on the second side connected to the lower group, and a number of layers of the connection gate electrodes to which the gate contact portions are connected sequentially increases as a distance from a boundary between the first group and the second group increases.
