Abstract
A memory device includes a memory cell array connected to a plurality of word lines, a clock generator configured to generate a clock signal, a charge pump circuit configured to generate a voltage to be provided to the plurality of word lines, based on the clock signal, a row decoder configured to provide the voltage to a selected memory block, a current generation circuit connected in parallel to a word line path through which the voltage is provided from the charge pump circuit to the row decoder and configured to generate a current flowing through the word line path for a reference time, and a defect detection circuit configured to detect a defect on the word line path by comparing a first count value of the clock signal counted before the reference time with a second count value of the clock signal counted after the reference time.
