Zusammenfassung:According to the present technology, provided is a read reference voltage determination apparatus, which includes: a threshold voltage distribution estimation network which generates an estimate distribution using the feature distribution generated from the threshold voltage distribution for a plurality of pages and read attempt information; and a read reference voltage estimation network which generates a read reference voltage from the estimate distribution. The read attempt information includes a read attempt vector and an output value generated by applying the read attempt vector to the threshold voltage distribution for a page to be read among a plurality of threshold voltage distributions. 본 기술에 의한 읽기 기준 전압 결정 장치는 다수의 페이지에 대한 문턱 전압 분포로부터 생성된 특징 분포와 읽기 시도 정보를 이용하여 추정 분포를 생성하는 문턱 전압 분포 추정 네트워크; 및 추정 분포로부터 읽기 기준 전압을 생성하는 읽기 기준 전압 추정 네트워크를 포함하되, 읽기 시도 정보는 읽기 시도 벡터와 다수의 문턱 전압 분포 중 읽기 대상이 되는 페이지에 대한 문턱 전압 분포에 읽기 시도 벡터를 적용하여 생성한 출력값을 포함한다.
