Abstract
A data storage device may perform a method that includes identifying a first life stage of multiple life stages of the data storage device. The method includes determining a first health scheme based on the first life stage and generating a first health indicator associated with a region of the memory based on the first health scheme.
Claims30
A method comprising:
- in a data storage device that includes a memory, performing:
- identifying a first life stage of multiple life stages of the data storage device;
- determining a first health scheme based on the first life stage;
- and
- generating a first health indicator associated with a region of the memory based on the first health scheme.
2 more elements
A data storage device comprising:
- a memory including multiple storage elements;
- and
- a controller coupled to the memory, wherein the controller is configured to track one or more metrics associated with the memory and to determine, based on the one or more metrics, a transition from a first life stage of the memory to a second life stage of the memory, and wherein the controller is further configured to modify one or more weight values associated with a health scheme based on the transition to the second life stage.
A method comprising:
- in a data storage device that includes a memory, performing:
- receiving a request to perform a memory operation;
- responsive to the request, identifying a particular health indicator of multiple health indicators based on a value of the particular health indicator, wherein each health indicator corresponds to a different region of the memory and is generated based on a health scheme applied based on a life stage of the memory;
- and
- initiating the memory operation to be performed at a region of the memory that corresponds to the particular health indicator.

A method comprising:
- in a host device coupled to a first data storage device and coupled to a second data storage device, performing:
- identifying a first life stage of a first set of multiple life stages of the first data storage device;
- determining a first health value associated with a first memory of the first data storage device based on a first health scheme selected based on the first life stage;
- identifying a second life stage of a second set of multiple life stages of the second data storage device;
- determining a second health value associated with a second memory of the second data storage device based on a second health scheme selected based on the second life stage;
- and
- selecting one of the first data storage device or the second data storage device based on the first health value and the second health value for a write operation.
