A solid state drive with a Logical To Physical (L2P) indirection table stored in a persistent memory is provided. The L2P indirection table has a plurality of entries, each entry to store a physical block address in the block addressable memory assigned to a logical block address. The solid state drive including solid state drive controller circuitry communicatively coupled to the persistent memory and the block addressable memory. The solid state drive controller circuitry including a volatile memory to store a logical to physical address indirection table cache and circuitry to monitor the logical to physical address indirection table cache and to write dirty logical to physical entries in the logical to physical address indirection table cache to the logical to physical address indirection table in the persistent memory.

Logical to physical address indirection table in a persistent memory in a solid state drive

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

A multilevel memory subsystem includes a persistent memory device that can access data chunks sequentially or randomly to improve read latency, or can prefetch data blocks to improve read bandwidth. A media controller dynamically switches between a first read mode of accessing data chunks sequentially or randomly and a second read mode of prefetching data blocks. The media controller switches between the first and second read modes based on a number of read commands pending in a command queue.

Dynamically changing between latency-focused read operation and bandwidth-focused read operation

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.
