US 11,899,938 B2 · Techniques to reduce write amplification

Abstract

Methods, systems, and devices for techniques to reduce write amplification are described. A memory device may receive a write command from a host device and may determine that a quantity of commands stored in a buffer for execution by a memory array satisfies a first threshold. In some examples, the memory device may identify whether a write amplification parameter associated with the memory array satisfies a second threshold. The memory device may write data associated with the write command to the memory array using a first mode to write the data or a second mode to write the data based on determining that the quantity of commands satisfies the first threshold and/or identifying whether the write amplification parameter satisfies the second threshold. In some examples, the memory device may adjust a value of the first threshold or the second threshold or both based on the write amplification parameter.

Dependent claims

An apparatus, comprising:

a memory array;
and
a controller coupled with the memory array and configured to cause the apparatus to:
receive a write command from a host device;
determine whether a quantity of commands stored in a buffer for execution by the memory array satisfies a first threshold;
if the quantity of commands stored in the buffer fails to satisfy the first threshold, determine a ratio of a total quantity of data written to the memory array to a quantity of data requested to be written to the memory array by the host device;
and
write data associated with the write command to the memory array using a first mode to write data or a second mode to write data,
wherein the data is written using the first mode based at least in part on the quantity of commands satisfying the first threshold or the ratio failing to satisfy a second threshold, and
wherein the data is written using the second mode based at least in part on the quantity of commands failing to satisfy the first threshold and the ratio satisfying the second threshold.
