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.
