US 11,907,556 B2 · Data relocation operation techniques

Abstract

Methods, systems, and devices for data relocation operation techniques are described. A memory system may include blocks of memory cells, for example, within a non-volatile memory device of the memory system. The memory system may identify a command to perform a data relocation operation associated with a block of memory cells and may select between a first procedure and a second procedure for performing the data relocation operation. The memory system may select between the first procedure and the second procedure based on whether one or more parameters associated with the data relocation operation satisfy a threshold. For example, the memory system may select the first procedure if the one or more parameters satisfy the threshold and may select the second procedure if the one or more parameters do not satisfy the threshold. The memory system may perform the data relocation operation using the selected procedure.

Dependent claims

A memory system, comprising:

one or more memory devices;
and
processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
identify a command to perform a data relocation operation associated with a block of memory cells of the memory system;
select between a first procedure for performing the data relocation operation and a second procedure for performing the data relocation operation based at least in part on whether one or more parameters associated with the data relocation operation satisfy a threshold;
perform the data relocation operation using the first procedure or the second procedure based at least in part on identifying the command and selecting between the first procedure and the second procedure;
and
determine whether to update a mapping that indicates relationships between logical addresses and physical addresses based at least in part on whether the data relocation operation is performed using the first procedure or the second procedure.

5 more elements

A non-transitory computer-readable medium storing code comprising instructions which, when executed by one or more processors of a memory system, cause the memory system to:

identify a command to perform a data relocation operation associated with a block of memory cells of the memory system;
select between a first procedure for performing the data relocation operation and a second procedure for performing the data relocation operation based at least in part on whether one or more parameters associated with the data relocation operation satisfy a threshold;
perform the data relocation operation using the first procedure or the second procedure based at least in part on identifying the command and selecting between the first procedure and the second procedure;
and
determine whether to update a mapping that indicates relationships between logical addresses and physical addresses based at least in part on whether the data relocation operation is performed using the first procedure or the second procedure.
