Abstract
An operating method of a storage device is provided. The storage device includes a nonvolatile memory and a memory controller to control the nonvolatile memory. Temperature is detected. A current weighted time is calculated using the temperature. Data is read from the nonvolatile memory using a read voltage level which is adjusted based on the current weighted time. The current weighted time is determined according to an amount of charges leaked from memory cells storing the data at the temperature.
