Semiconductor device

Abstract

Disclosed is a semiconductor device, including: a memory block including a plurality of memory strings, each of the memory strings including a drain select transistor coupled to a bit line, a source select transistor coupled to a common source line, memory cells coupled to the drain select transistor and the source select transistor, and dummy memory cells coupled to the drain select transistor and the memory cell; and an operation circuit configured to perform a program operation on the memory cells. The operation circuit generates operation voltages applied to the dummy memory cells so that electric charges are generated by a band to band tunneling effect in the dummy memory cell adjacent to the drain select transistor during the program operation.

Dependencies are inferred from the claim text.
