Abstract
A memory device includes a memory, a secure-access circuit, a plain-access circuit, and protection hardware. The memory includes at least a secure-storage partition assigned a first address range and a plain-storage partition assigned a second address range, disjoint from the first address range. The secure-access circuit is configured to access the secure-storage partition by generating addresses in the first address range. The plain-access circuit is configured to access the plain-storage partition by generating addresses in the second address range. The protection hardware is configured to prevent the plain-access circuit from accessing the first address range assigned to the secure-storage partition.
