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.

End-to-end data protection for far memory data transfer from host to media

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.

Data transfer method and apparatus for differential data granularities

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.

Preset evaluation to improve input/output performance in high-speed serial interconnects

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.
