    • 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.
    • 存储器件包括存储器阵列,与存储器阵列耦合的状态寄存器,以及与存储器阵列和状态寄存器耦合的安全寄存器。 存储器阵列包含被配置为具有独立访问控制的多个存储器块。 状态寄存器包括至少一个保护位,指示对应于保护位的存储器块的至少一个相应块的写保护状态。 安全寄存器包括至少一个寄存器保护位。 寄存器保护位可编程为存储器保护状态,以防止至少状态寄存器的保护位的状态改变。 寄存器保护位被配置为保持存储器保护状态,直到存储器件的复位。
