    Abstract: Examples are disclosed for probabilistic dynamic random access memory (DRAM) row repair. In some examples, using a row hammer limit for DRAM and a maximum activation rate for the DRAM a probabilistic row hammer detection value may be determined. The probabilistic row hammer detection value may then be used such that a probability is acceptably low that a given activation to an aggressor row of the DRAM causes the row hammer limit to be exceeded before a scheduled row refresh is performed on one or more victim rows associated with the aggressor row. Other examples are described and claimed.

    Abstract: A shared memory controller receives a flit from another first shared memory controller over a shared memory link, where the flit includes a node identifier (ID) field and an address of a particular line of the shared memory. The node ID field identifies that the first shared memory controller corresponds to a source of the flit. Further, a second shared memory controller is determined from at least the address field of the flit, where the second shared memory controller is connected to a memory element corresponding to the particular line. The flit is forwarded to the second shared memory controller using a shared memory link according to a routing path

    Abstract: A server, processing device and/or processor includes a processing core and a memory controller, operatively coupled to the processing core, to access data in an off-chip memory. A memory encryption engine (MEE) may be operatively coupled to the memory controller and the off-chip memory. The MEE may store non-MEE metadata bits within a modified version line corresponding to ones of a plurality of data lines stored in a protected region of the off-chip memory, compute an embedded message authentication code (eMAC) using the modified version line, and detect an attempt to modify one of the non-MEE metadata bits by using the eMAC within a MEE tree walk to authenticate access to the plurality of data lines. The non-MEE metadata bits may store coherence bits that track changes to a cache line in a remote socket, poison bits that track error containment within the data lines, and possibly other metadata bits.
