Embodiment Construction

[0018] Referring now to the figures, there are shown systems and methods for offloading data processing from a host to a hybrid solid state device (HSSD). In some embodiments, the HSSD receives data from the host and stores the data in a first non-volatile memory (NVM). In this case, the HSSD may receive translation commands from the host and, based on the commands, translate the data using the processing circuitry and the second NVM providing a finer granularity of data access than the first NVM. The command may cause the HSSD to copy data from the first NVM to the second NVM and perform one or more data conversion operations on the data on the second NVM. After conversion, the HSSD may store the converted data in the first NVM and / or the second NVM. Upon request, HSSD can send the converted data to the host. Therefore, data conversion operations can be offloaded from the host.

Abstract

Systems and methods for offloading data transformation from a host to a hybrid solid state drive (HSSD) are described. In one such method, the HSSD receives initial data from the host and stores the data at a first non-volatile memory (NVM). The HSSD receives a transformation command from the host to offload data transformation. The HSSD copies the data from the first NVM to a second NVM that is configured to provide a finer granularity of data access than that of the first NVM. Then the HSSD transforms the data at the second NVM utilizing the configured processing circuit. The HSSD may storethe result in the first NVM and / or second NVM, and send it to the host.

Description

technical field [0001] Aspects of the present disclosure relate generally to solid-state storage, and more particularly, to hybrid solid-state storage devices that use different types of data storage. Background technique [0002] In a variety of consumer electronics and computers, solid-state drives incorporating non-volatile memory (NVM) often replace or supplement traditional spinning hard drives for mass storage. These non-volatile memories may include one or more flash memory devices, which may be logically divided into blocks, and each block may be further logically divided into addressable pages. In some applications, the host can read data from a solid-state drive (SSD), perform transformations on the data, and write the transformed data back to the SSD. However, the input and output stack or interface between the host and the SSD may present a bottleneck, limiting the speed at which the host can convert data stored in the SSD. Contents of the invention [0003] ...
