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.
