Abstract: A multilevel memory system includes a nonvolatile memory (NVM) device with an NVM media having a media write unit that is different in size than a host write unit of a host controller of the system that has the multilevel memory system. The memory device includes a media controller that controls writes to the NVM media. The host controller sends a write transaction to the media controller. The write transaction can include the write data in host write units, while the media controller will commit data in media write units to the NVM media. The media controller can send a transaction message to indicate whether the write data for the write transaction was successfully committed to the NVM media.

Abstract: A multi-level memory architecture scheme to dynamically balance a number of parameters such as power, thermals, cost, latency and performance for memory levels that are progressively further away from the processor in the platform based on how applications are using memory levels that are further away from processor cores. In some examples, the decision making for the state of the far memory (FM) is decentralized. For example, a processor power management unit (p-unit), near memory controller (NMC), and/or far memory host controller (FMHC) makes decisions about the power and/or performance state of the FM at their respective levels. These decisions are coordinated to provide the most optimum power and/or performance state of the FM for a given time. The power and/or performance state of the memories adaptively change to changing workloads and other parameters even when the processor(s) is in a particular power state.

Abstract: Apparatuses, storage media and methods associated with data transfer, are disclosed herein. In some embodiments, an apparatus for computing comprises: a commit generator and a media write generator. The commit generator is arranged to generate commit indicators correspondingly associated with media slices of a storage media to respectively denote to a storage media controller of the storage media whether to proceed with writing the media slices into the storage media. The media write generator is arranged provide data chunks of the media slices to be written into the storage media, and the associated commit indicators to the storage media controller. A size of each data chunk is smaller than a size of each media slice. Other embodiments are also described and claimed.

Abstract: Systems, apparatuses and methods may provide for technology to add non-address metadata to a memory address field of a transaction layer packet (TLP), wherein the non-address metadata includes one or more vendor-specific attributes. Additionally, the technology may coordinate between a transmitter and a receiver to prevent the TLP from violating an address boundary constraint associated with an interface. In one example, the address boundary constraint prohibits an address and length combination of the TLP from crossing a 4-KB boundary.

Abstract: Methods and apparatus for utilization of preset evaluation to improve input/output performance in high-speed serial interconnects are described. In some embodiments, performance of a link is evaluated at a plurality of equalization values and one of the plurality of equalization values is selected for the link based on comparison of a plurality of margin values that are to be determined for each of the plurality of equalization values. Other embodiments are also claimed and/or disclosed.

Abstract: A method and apparatus to deskew dead cycles is described using a block aligner. In one example a method includes receiving a sequence of bytes into a first buffer from each lane of a multiple lane peripheral device bus and receiving the sequence of bytes into a second buffer delayed one clock cycle from the first buffer. The method further includes providing the sequence of bytes from the first buffer to an output buffer, counting clock cycles of data as the data is received into the first and second buffers, upon reaching a predetermined count, inserting a dead cycle into the output buffer, and after inserting the dead cycle providing the sequence of bytes from the second buffer instead of the first buffer to the output buffer.
