TECHNOLOGIES FOR MANAGING A DYNAMIC READ CACHE OF A SOLID STATE DRIVE

摘要

Technologies for managing a read cache of a solid state drive include establishing a read cache in an otherwise unused region of non-volatile memory of the solid state drive. To do so, a memory region of the non-volatile memory corresponding to the read cache is converted to single-level cell (SLC) mode. For example, the memory region may be converted from a multi-level cell (MLC) or a triple-level cell (TLC) mode to the SLC mode. A drive controller of the solid state drive manages data in the read cache based on a read count associated with the data. For example, data having a relatively high read count may be inserted into the read cache and data having a relatively lower read count may be evicted from the read cache over time. The size of the read cache may be dynamically adjusted over time based on available space and/or operating requirements.
