Abstract
A method of setting a read voltage by a memory controller and a storage device are provided. The method includes controlling a memory device to read data from memory cells by applying a test read voltage to a selected word line; receiving, from the memory device, cell count information corresponding to a read operation of the memory device, and renewing the test read voltage by using the cell count information and a cost function to find an optimum read voltage, the cost function being determined for each read voltage level; and determining a read voltage by performing the controlling of the memory device and the renewing of the test read voltage at least once.
