Abstract
A storage device includes a nonvolatile memory device, a buffer memory, a controller and a neuromorphic chip. The neuromorphic chip is configured to generate an access classifier based on the access result information and the access environment information. The controller is configured to perform first accesses to the nonvolatile memory device using the buffer memory and to collects the access result information and the access environment information of the first accesses in the buffer memory. The controller is configured to perform a second access of the nonvolatile memory device using the buffer memory. The controller is configured to obtain a prediction result of access parameters associated with the second access by using access environment information associated with the second access and the access classifier.

20. An access method of a nonvolatile memory device, the method comprising:
-
performing first accesses to the nonvolatile memory device to collect first access result information and first access environment information of the first accesses; generating an access classifier, the generating the access classifier including performing machine learning based on the collected first access result information and the collected first access environment information; obtaining, before performing a second access on the nonvolatile memory device, a prediction result of access parameters associated with the second access by using second access environment information of the second access and the access classifier; performing the second access on the nonvolatile memory device using the prediction result; and updating the access classifier to apply second access result information of the second access and the second access environment information of the second access to the access classifier.
