Abstract: An apparatus is described that includes a memory card. The memory card also includes volatile memory devices. The memory card also includes non volatile memory devices. The memory card is configurable to implement a first portion of the storage space of the non volatile memory devices as system memory. The memory card also includes a controller to manage, upon a power down event, the transfer of information from the volatile memory devices into a second portion of the storage space of the non volatile memory devices.

Abstract: Techniques for tamper detection of a memory module having non-volatile memory devices resident on a printed circuit board (PCB) by circuitry of a controller also resident on the PCB. Examples include determining resistance values of a character pattern sprayed on a side of a cover facing the non-volatile memory devices using conductive ink following first and second boots of the memory module and asserting a bit of a register to indicate tampering of the memory modules based on a comparison of the resistance values. Tamper policy actions may be initiated based on detection of tampering.

Abstract: A method is described. The method includes recognizing higher priority users of a multi-level system memory characterized by a faster higher level and a slower lower level in which the higher level is to act as a cache for the lower level and in which a first capacity of the higher level is less than a second capacity of the lower level such that caching resources of the higher level are oversubscribe-able. The method also includes performing at least one of: declaring an amount of the second capacity un-useable to reduce oversubscription of the caching resources; allocating system memory address space of the multi-level system memory so that requests associated with lower priority users will not compete with requests associated with the higher priority users for the caching resources.
