Patent number: 11630765Abstract: The subject matter described herein provides systems and techniques to counter a high write amplification in physical memory, to ensure the longevity of the physical memory, and to ensure that the physical memory wears in a more uniform manner. In this regard, aspects of this disclosure include the design of a Flash Translation Layer (FTL), which may manage logical to physical mapping of data within the physical memory. In particular, the FTL may be designed with a mapping algorithm, which uses reinforcement learning (RL) to optimize data mapping within the physical memory. The RL technique may use a Bellman equation with q-learning that may rely on a table being updated with entries that take into account at least one of a state, an action, a reward, or a policy. The RL technique may also make use a deep neural network to predict particular values of the table.Type: GrantFiled: December 14, 2020Date of Patent: April 18, 2023Assignee: Google LLCInventors: Shashwat Silas, Narges Shahidi, Tao Gong, Manuel Benitez

Publication number: 20230019966Abstract: A drive placement or placement functionality can enable initial copies of data to be placed on a drive in reclaim unit (HRUs) in a manner which is probabilistically more efficient from a garbage collection (GC) perspective and leverages knowledge of a host or application using the data. The placement functionality enables the advantages of fine-grained placement functionality while simultaneously allowing a storage device or storage drive to maintain NAND or other management responsibility, and not allocate that responsibility to an application or host device using the device.Type: ApplicationFiled: July 13, 2022Publication date: January 19, 2023Inventors: Christopher Sabol, Manuel Benitez
