Abstract
Various embodiments relate to a memory controller, including: a memory interface connected to a memory; an address and control logic connected to the memory interface and a command interface, wherein the address and control logic is configured to receive a memory read request; a read inline encryption engine (IEE) connected to the memory interface, wherein the read IEE is configured to decrypt encrypted data read from the memory; a key selector configured to determine a read memory region associated with the memory read request based upon a read address where the data to be read is stored, wherein the read address is received from the address and control logic; and a key logic configured to select a first key associated with the determined read memory region and provide the selected key to the read IEE.
