15. A method of operating a controller for controlling a semiconductor memory device, the method including:
-
comparing event signals input through a plurality of event signal lines with an event expectation value representing states of the event signals when an event occurs, thereby detecting the occurrence of the event; generating event information including event data from a preset time before and after a point of time when the event occurs; and generating a command for storing the event information in the semiconductor memory device. - View Dependent Claims (16, 17, 18, 19, 20)
