Abstract
According to an embodiment, an information processing system includes a time constant processor and a pattern generator. The time constant processor binarizes values indicating a plurality of unit circuits each including a gate insulating film on the basis of a time to emission indicating a time from when a defect in the gate insulating film captures a carrier in a channel current caused to flow by application of a gate voltage to the unit circuits to when the defect emits the carrier. The pattern generator generates a pattern unique to the unit circuits using the values indicating the respective unit circuits binarized by the time constant processor.
