    Abstract: An operation method of a storage controller which includes a nonvolatile memory device, the method including: collecting a first parameter indicating a degradation factor of a first memory area of the nonvolatile memory device and a second parameter indicating a degree of degradation occurring at the first memory area, in an initial driving period; selecting a first function model of a plurality of function models based on the first parameter and the second parameter and predicting a first error tendency of the first memory area based on the first function model; determining a first reliability interval based on the first error tendency; and performing a first reliability operation on the first memory area of the nonvolatile memory device based on the first reliability interval.

    Abstract: A memory system includes multiple storage devices that each include a nonvolatile memory device. A client device is configured to collect deterioration information of the nonvolatile memory devices provided from the storage devices. A server device is configured to receive the collected deterioration information and to predict a degree of deterioration of the nonvolatile memory devices in real time by performing machine learning based on the collected deterioration information and initial deterioration information. The client device determines a read level of the nonvolatile memory device based on the degree of deterioration of the nonvolatile memory devices from the server device. The storage device sets the nonvolatile memory device to operate based on the read level determined in the client device.

    Abstract: A storage device includes a nonvolatile memory having a plurality of memory cells and a memory controller to control the nonvolatile memory. The operating method of the storage device includes reading previously programmed memory cells among the memory cells of the nonvolatile memory and determining a time after erase of the previously programmed memory cells, programming selected memory cells of the nonvolatile memory, and programming meta data including a time after erase of the selected memory cells, based on the determined time after erase of the previously programmed memory cells.
