Abstract:
Aspects of the disclosure provide for control of a flash translation layer (FTL) in a non-volatile memory (NVM). Disclosed methods and apparatus provide for receiving a message in the FTL, which is transmitted from a host device, and includes desired recycle ratio information that is determined by the host where the ratio is a number of host writes to a number of recycle writes to be performed by the FTL. Based on the recycle ratio information, the FTL determines a target recycle ratio and performs recycling of memory blocks in the NVM based on the determined target recycle ratio. In this manner, the host device is able to exert control over the recycle ratio utilized in the FTL via a transmitted message, which allows the recycle ratio to be more adaptive to host write conditions known to the host device, but not known in the SSD.

Claim (Index 17):
A non-volatile memory (NVM) device including an apparatus for control of a flash translation layer (FTL) in the NVM device, the apparatus comprising:\n means for receiving a message from a host device, the message including user recycle ratio information determined in the host device where the user recycle ratio information communicates a desired ratio of a number of host writes to a number of recycle writes to be performed by the FTL; means for determining a target recycle ratio based on the received user recycle ratio information; and means for performing recycling of memory blocks in the NVM based on the determined target recycle ratio.
