SEMICONDUCTOR DEVICE

摘要

A semiconductor device according to an embodiment may include a memory string including a drain selection transistor, memory cells and a source selection transistor all coupled between a bit line and a common source line, and the drain selection transistor, the memory cells and the source selection transistor configured to operate, respectively, in response to voltages applied to a drain selection line, word lines and a source selection line. The semiconductor device may include an operation circuit configured for performing a program operation. The operation circuit may be configured for sequentially performing a first operation, a second operation, and a third operation. In the first operation memory cells adjacent to the drain selection transistor may be programmed. In the second operation memory cells adjacent to the source selection transistor may be programmed. In the third operation remaining memory cells may be programmed.
