Zusammenfassung:The present invention relates to a semiconductor device and an operating method thereof, capable of processing a plane, which is failed in an erase verification operation, as fail and normally using the remaining planes during a multi-plane operation. According to the present invention, the method comprises the following steps: performing an erase loop until an erase verification operation of multiple planes is passed; determining whether the planes passing the erase verification operation exist among the multiple planes when the erase verification operation is failed until the number of times of the erase loop attains the maximum number of times; and terminating operation of the failed planes and performing a soft programming operation of the passed planes when the passed planes exist. 본 기술은 다수의 플래인들의 소거 검증 동작이 패스(pass)될 때까지 소거 루프(loop)를 수행하는 단계; 상기 소거 루프의 횟수가 최대 횟수에 도달할 때까지 상기 소거 검증 동작이 페일(fail)되면, 상기 다수의 플래인들 중 상기 소거 검증 동작이 패스된 플래인들이 있는지를 판단하는 단계; 및 상기 패스된 플래인들이 있으면, 상기 페일된 플래인들의 동작을 종료하고, 상기 패스된 플래인들의 소프트 프로그램 동작을 수행하는 단계를 포함하는 반도체 장치 및 이의 동작 방법을 포함한다.
