摘要
One-time programmable (OTP) and write-once read-many (WORM) memory devices and methods for use therewith are provided. These embodiments can be used to provide compatibility between a memory device that uses an OTP (or few-time programmable (FTP)) memory array and host devices that use a file system, such as the DOS FAT file system, that expects to be able to rewrite to a memory address in the memory device. These embodiments can also be used to prevent accidental or deliberate overwrites, changes, or deletions to existing data in a WORM memory device.
