Abstract: A memory device may determine cell count information from a threshold voltage distribution of memory cells and may determine a detection case based on cell count information when correction of an error in read data, received from the memory device performing a read operation, fails. The memory controller may control the memory device to perform a read operation using a development time determined in consideration of an offset voltage of a read voltage corresponding to the detection case. When correction of the error in the read data fails again, the memory controller may control the memory device to perform a read operation using a corrected read voltage generated using a dynamic offset voltage obtained by inputting the cell count information to a machine learning model.
