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 13):
The SSD of  claim 9 , wherein the controller is further configured to:\n calculate a flash translation layer (FTL) recycle ratio; determine a user recycle ratio based on the received user recycle ratio information; compare the FTL recycle ratio with the user recycle ratio; and set the target recycle ratio equal to the FTL recycle ratio when the FTL recycle ratio is less than the user recycle ratio and setting the target recycle ratio equal to the user recycle ratio when the FTL recycle ratio is greater than or equal to the user recycle ratio.
