Abstract:
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.
