More Information
Summary:According to an embodiment of the present disclosure, a non-volatile memory device communicates with a storage controller. An operating method of a non-volatile memory device includes the steps of: indicating a read reclaim decision from a storage controller and receiving a first request including environmental information; performing a first on-chip read operation to generate first distribution information, based on the first request; determining whether lead reclaim is required, based on the first distribution information; and providing a decision result having a first bit value to the storage controller, in response to determining that the lead claim is required. 본 개시의 일 실시 예에 따른 비-휘발성 메모리 장치는 스토리지 컨트롤러와 통신한다. 비-휘발성 메모리 장치의 동작하는 방법은, 스토리지 컨트롤러로부터 리드 리클레임 결정을 가리키고 그리고 환경 정보를 포함하는 제1 요청을 수신하는 단계, 제1 요청에 기초하여, 제1 산포 정보를 생성하기 위해 제1 온-칩 읽기 동작을 수행하는 단계, 제1 산포 정보에 기초하여, 리드 리클레임이 요구되는지 여부를 결정하는 단계, 및 리드 리클레임이 요구된다고 결정한 것에 응답하여, 제1 비트 값을 갖는 결정 결과를 스토리지 컨트롤러에게 제공하는 단계를 포함한다.
