Witryna좋은 자료를 제공해주셔서 정말 감사합니다. 본 문서는 NAND에 대한 학부 수준의 내용을 총정리한 문서입니다. 부족하거나 틀린 내용에 대한 지적은 언제나 반갑습니다. 1. NAND의 구조. 1.1. NAND cell 구조와 구성의 이해. NAND memory cell은 MOS capacitor의 일종으로 1개의 ... Witryna6 sie 2015 · Since NAND Flash’s theory of operation is based on tunnelling, it’s based on a quantum effect, which means that it is probabilistic. In other words, we can’t guarantee that we’ve fully charged a floating gate to the point that it will read out as a zero during the next page read. The controller can maintain the bit line/word line ... mulch install price
