CACHE MEDIA MANAGEMENT

Abstract:

An exempt portion of a data cache of a memory sub-system is identified. The exempt portion includes a first set of data blocks comprising first data written by a host system to the data cache. A collected portion of the data cache of the memory sub-system is identified. The collected portion includes a second set of data blocks comprising second data written by the host system. A media management operation is performed on the collected portion of the data cache to relocate the second data to a storage area of the memory sub-system that is at a higher data density than the data cache, wherein the exempt portion of the data cache is exempt from the media management operation.
