Storage Devices Including Nonvolatile Memory Devices and Access Methods for Nonvolatile Memory Devices

A storage device is provided and may include a nonvolatile memory device, a buffer memory, and a controller. The controller may perform first accesses on the nonvolatile memory device using the buffermemory, collect access result information and access environment information of the first accesses in the buffer memory, and generate an access classifier that predicts a result of a second access tothe nonvolatile memory device by performing machine learning based on the access result information and the access environment information collected in the buffer memory. 本发明提供了种存储装置，其可包括非易失性存储器装置、缓冲器存储器和控制器。控制器可利用缓冲器存储器对非易失性存储器装置执行第访问；在缓冲器存储器中收集第访问的访问结果信息和访问环境信息；以及基于在缓冲器存储器中收集的访问结果信息和访问环境信息，通过执行机器学习来产生访问分类器，访问分类器预测对非易失性存储器装置的第二访问的结果。
