摘要:
A processor includes a first memory interface to be coupled to a plurality of dual in-line memory module (DIMM) sockets located off-package, a second memory interface to be coupled to a non-volatile memory (NVM) socket located off-package, and a multi-level memory controller (MLMC). The MLMC is to: control the DIMMs disposed in the plurality of DIMM sockets as main memory in a one-level memory (1LM) configuration; detect a switch from a 1LM mode of operation to a two-level memory (2LM) mode of operation in response to a basic input/output system (BIOS) detection of a low-power DIMM disposed in one of the DIMM sockets and a NVM device disposed in the NVM socket in a 2LM configuration; and control the low-power DIMM as cache in the 2LM configuration in response to detection of the switch from the 1LM mode of operation to the 2LM mode of operation.
