Computing device, computing system and computing method

Abstract

Memory devices, circuits, and a method of operating the same are disclosed. In one aspect, a computing device includes a plurality of memory devices and a memory controller. The memory controller includes an encrypted memory map. The memory controller can decrypt the encrypted memory map to generate a decrypted memory map that defines memory locations of a plurality of code regions of the memory devices. The memory controller can retrieve microcode and a protection key using the memory locations of the code regions. The memory controller can validate the microcode and the protection key and execute the microcode using the protection key.
