Abstract
A page buffer circuit includes a bit line selection circuit, a main register, a program transmission circuit, a temporary register, and a verification transmission circuit. The verification transmission circuit transmits data stored in the temporary register to the main register through a sensing node in response to a transmission control signal during a program verification operation. A memory cell that has been determined to be programmed in a previous program verification process is verified again in a next program verification process.
