Abstract
A method of operating a semiconductor memory device includes starting a program operation on selected memory cells using a main verification voltage and an auxiliary verification voltage in response to a program command, receiving a program suspend command during the program operation, and changing at least one auxiliary voltage verification result information among threshold voltage states which are not program-passed to at least one data pattern among threshold voltage states which program-passed, in response to the program suspend command.
