...maybe?
- kosma 7y agoDefault erase state for NAND memory is ones.
- segfaultbuserr 7y agoIt's also true for most NOR memory and most earlier EEPROM and EPROM chips. This convention came from the original OTP memory - a "0" is created by burning the fuse to physically destroy an electrical link [0] on the chip, you can only change "1" to "0", not vice versa. [0] In physical implementation details, however, an antifuse is actually more common than a fuse, i.e. breaking the link (e.g. by a high voltage pulse) creates a short, not an open.
