Summary:A system architecture providing memory encryption suitable for protection against liquid nitrogen and trace probe attacks. In one embodiment, a method of and system for memory encryption are provided. A write request is received at a memory controller. The write request includes first data and a first address. The memory controller is embedded in a CPU and is operatively coupled to memory external to the CPU. The first data are encrypted at the memory controller to generate encrypted first data. The encrypted first data are written to the memory.
