Abstract
A storage device may include a memory device including a memory block including a plurality of strings each including a plurality of memory cells and configured to perform a threshold voltage detecting operation of detecting a threshold voltage corresponding to each of the plurality of strings by simultaneously applying a detecting voltage to a plurality of word lines coupled to the plurality of memory cells, and a memory controller configured to receive read data read by the threshold voltage detecting operation from the memory device, to determine a number of strings having a lower threshold voltage than the detecting voltage on the basis of the read data, and to determine whether to perform a refresh operation on the memory block based on the determined number of strings.
