Dynamic Buffer Management for Parallel Data Placement Handlers in a Data Storage Device

Abstract

A memory sub-system having a first memory configured as a non-volatile storage medium of the memory sub-system; and a second memory having an access speed faster than the first memory. A processing device of the memory sub-system is configured to: run a plurality of data placement handlers concurrently; allocate a plurality of data buffers from the second memory to the plurality of data placement handlers respectively; reserve a plurality of backup spaces from the first memory for the plurality of data placement handlers respectively; allocate accumulation buffers from the second memory; and arrange the data placement handlers to time share the accumulation buffers via usages of the backup spaces.
