Abstract
A storage device, including a feature information database configured to store feature information about a memory device; and a machine learning module configured to select a machine learning model from a plurality of machine learning models the corresponding to an operation of the memory device based on the feature information, wherein the memory device is configured to operate according to the selected machine learning model.
Claims20
A storage device comprising:
- a feature information database configured to store feature information about a memory device, wherein the feature information includes physical information relating to at least one of a manufacturing of the memory device and a physical arrangement of the memory device;
- and
- a machine learning module configured to select a machine learning model from a plurality of machine learning models corresponding to an operation of the memory device based on the feature information,
- wherein the memory device is configured to operate according to the selected machine learning model,
- wherein the physical information includes at least one from among a lot identifier, a chip number, a block address, and a wordline number.
2 more elements
A method of operating a storage device, the method comprising:
- determining whether an operation of a memory device corresponds to a plurality of machine learning models;
- based on determining that the operation of the memory device corresponds to the plurality of machine learning models, determining indirect information about the memory device;
- selecting a machine learning model from the plurality of machine learning models based on at least one from among direct information about the memory device or the indirect information about the memory device;
- and
- executing inference according to the machine learning model,
- wherein the direct information includes physical information about at least one of a manufacturing of the memory device and a physical arrangement of the memory device, and
- wherein the indirect information is determined based on the physical information,
- wherein the physical information includes at least one from among a lot identifier, a chip number, a block address, and a wordline number.
5 more elements
A storage device comprising:
- a memory device;
- and
- a storage controller configured to:
- select a machine learning model from a plurality of machine learning models based on feature information about the memory device, wherein the feature information includes physical information relating to at least one of a manufacturing of the memory device and a physical arrangement of the memory device,
- execute inference according to the selected machine learning model, and
- tune the selected machine learning model according to an error between an actual measured value in the memory device and a predicted value of the selected machine learning model based on the feature information,
- wherein the physical information includes at least one from among a lot identifier, a chip number, a block address, and a wordline number.
