Nor flash bit翻转
Web30 de nov. de 2024 · This arrangement is called "NOR flash" because it acts like a NOR gate. The fact that each cell has one end connected to a bit line means they (and so each bit) can be accessed randomly. NAND flash also uses floating-gate transistors, but they are connected in a way that resembles a NAND gate: several transistors are connected in … Web28 de set. de 2024 · Flash位反转由于Flash固有的特性,在读写数据过程中,偶然会产生一位或几位数据错误(这种概率很低),bit位从“1”变为“0”,或者从“1”变为“0”。当位反转发生在关键的代码、数据上时,有可能导致系统崩溃。当仅仅是报告位反转,重新读取即可:如果确实发生了位反转,则必须有相应的 ...
