Classification: CPC G | IPC G

Claim 0:
1. An operating method of a storage device which includes a nonvolatile memory device and a memory controller, the method comprising:
{circle around (1)} sending, at the memory controller, a first read command and first offset information to the nonvolatile memory device;
{circle around (2)} performing, at the nonvolatile memory device, first read operations based on the first read command and the first offset information;
{circle around (3)} sending, at the nonvolatile memory device, a result of the first read operations as first data to the memory controller;
{circle around (4)} sending, at the memory controller, a second read command, read voltage levels, and second offset information to the nonvolatile memory device;
{circle around (5)} performing, at the nonvolatile memory device, second read operations based on the second read command, the read voltage levels, and the second offset information;
{circle around (6)} sending, at the nonvolatile memory device, results of the second read operations as second data to the memory controller; and
{circle around (7)} predicting the second set information, based on the result of the first read operations and a machine learning-based offset prediction module included in the memory controller.
