    摘要： A method for verifying memory device integrity includes identifying at least one memory block corresponding to at least one memory location within a memory device. The memory block is associated with a prior checksum. It is determined whether the first memory block is designated read-only. A current checksum is calculated based at least in part on data within the memory block. When the first memory block is designated read-only, and the prior checksum represents expected data within the first memory block, it is determined whether the current checksum is equal to the prior checksum. When the current checksum is not equal to the prior checksum, a verification failure for the first memory block is indicated via a notification interface. A system for verifying memory device integrity is also disclosed.

    摘要翻译： 用于验证存储器件完整性的方法包括识别对应于存储器件内的至少一个存储器位置的至少一个存储器块。 内存块与先前的校验和相关联。 确定第一存储块是否被指定为只读。 至少部分地基于存储器块内的数据来计算当前校验和。 当第一存储器块被指定为只读时，并且先前校验和表示第一存储器块内的期望数据，则确定当前校验和是否等于先前的校验和。 当当前校验和不等于先前的校验和时，通过通知接口来指示第一存储器块的校验失败。 还公开了一种用于验证存储器件完整性的系统。
