MEMORY DEVICES WITH DATA PROTECTION |
摘要 |
A memory device comprises a memory array, a status register coupled with the memory array, and a security register coupled with the memory array and the status register. The memory array contains a number of memory blocks configured to have independent access control. The status register includes at least one protection bit indicative of a write-protection status of at least one corresponding block of the memory blocks that corresponds to the protection bit. The security register includes at least one register-protection bit. The register-protection bit is programmable to a memory-protection state for preventing a state change of at least the protection bit of the status register. The register-protection bit is configured to remain in the memory-protection state until the resetting of the memory device.
