A storage device configured to provide an improved data recovery rate includes a memory device including a plurality of memory cells and a memory controller. The memory controller includes a read operation controller for controlling the memory device to perform a read operation by applying a default read voltage or optimal read voltage to a selected word line coupled to selected memory cells among the plurality of memory cells; and an optimal read voltage operating component for determining the optimal read voltage when the read operation using the default read voltage fails, based on an average threshold voltage and cell number information which are information on a memory cell number for each of first and second distributions which are adjacent threshold voltage distributions among threshold voltage distributions that the threshold voltages of the selected memory cells form.

Storage device and operating method thereof

A method and apparatus for controlling an outgoing call during download of phone book information are provided. The method includes setting, by a controller, a communication channel with a user device when a vehicle is powered on. Additionally, the method includes transmitting, by the controller, a predetermined phone book download request signal to the user device via the set communication channel. The method may further include downloading, by the controller, new phone book information from the user device via the set communication channel. Furthermore, the method includes completing an outgoing call service request from a user using existing phone book information while new phone book information is downloaded.
