Abstract
An operating method of a semiconductor memory device may include receiving a command, outputting a status signal as a busy status while accessing a selected area of the memory cell array in response to the command, changing the status signal from the busy status to a ready status and outputting the status signal after the access is completed, and applying a dummy pulse to an unselected area of the memory cell array in response to the status signal being output as the ready status.
