(This is called "multiple-write" in the YAFFS article). immaculate heart rosaryWeb\$\begingroup\$ @JoelFernandes Although you technically could design a NOR flash to be capable of individual cell erasure, that's not done in practice. Because it requires a high negative voltage, not a 0 or a 1, to erase a cell, they link many cells up into blocks to perform this erase operation. immaculate heart radio stations
