Logical to Physical Translation Table Adapted to Facilitate Tracking of Data of a Storage Space of a Memory Sub-System Cached or Buffered in a Memory Space of the Memory Sub-System

A memory sub-system, comprising:

• memory cells of a first type to provide a memory space;
• memory cells of a second type to provide a physical storage space;
• and
• a controller configured to:
• store a plurality of entries in a logical to physical translation table, each respective entry in the plurality of entries configured to identify mapping between a portion of a logical storage space and a portion of the physical storage space of the memory sub-system;
• and
• store, in the memory space, a copy of a data portion addressable in the logical storage space.

A non-transitory computer storage medium storing instructions which, when executed in a memory sub-system, cause the memory sub-system to perform a method, comprising:

• maintaining a plurality of entries in a logical to physical translation table, each respective entry in the plurality of entries configured to identify mapping between a portion of a logical storage space and a portion of a physical storage space of the memory sub-system;
• caching or buffering, in a memory space of the memory sub-system, a data portion addressable in the logical storage space;
• and
• configuring a first entry, among the plurality of entries, to indicate that the data portion is cached or buffered in the memory space.
