US 2022/0188237 A1 · UNMAP OPERATION TECHNIQUES

Abstract

Methods, systems, and devices for unmap operation techniques are described. A memory system may include a volatile memory device and a non-volatile memory device. The memory system may receive a set of unmap commands that each include a logical block address associated with unused data. The memory system may determine whether one or more parameters associated with the set of unmap commands satisfy a threshold. If the one or more parameters satisfy the threshold, the memory system may select a first procedure for performing the set of unmap commands different from a second procedure (e.g., a default procedure) for performing the set of unmap commands and may perform the set of unmap commands using the first procedure. If the one or more parameters do not satisfy the threshold, the memory system may perform the set of unmap commands using the second procedure.

Dependent claims

An apparatus, comprising:

a memory system comprising a volatile memory device and a non-volatile memory device;
a controller coupled with the memory system and operable to cause the apparatus to:
receive a plurality of unmap commands, each unmap command of the plurality of unmap commands comprising a logical block address associated with unused data;
determine whether one or more parameters associated with the plurality of unmap commands satisfy a threshold;
select a first procedure for performing the plurality of unmap commands different from a second procedure for performing the plurality of unmap commands based at least in part on determining that the one or more parameters satisfy the threshold;
and
perform the plurality of unmap commands using the first procedure.

4 more elements

A non-transitory computer-readable medium storing code comprising instructions which, when executed by a processor of an electronic device, cause the electronic device to:

receive a plurality of unmap commands, each unmap command of the plurality of unmap commands comprising a logical block address associated with unused data;
determine whether one or more parameters associated with the plurality of unmap commands satisfy a threshold;
select a first procedure for performing the plurality of unmap commands different from a second procedure for performing the plurality of unmap commands based at least in part on determining that the one or more parameters satisfying the threshold;
and
perform the plurality of unmap commands using the first procedure.
