Abstract
A memory device may include a normal cell which is configured to be programmed to a first resistance and stabilized as a resistance of the normal cell drifts from the first resistance to a second resistance; a flag cell which is configured to be programmed to a third resistance smaller than the first resistance and stabilized as a resistance of the flag cell drifts from the third resistance to a fourth resistance smaller than the second resistance; and a decision circuit which is configured to decide whether the flag cell has been stabilized in order to determine whether the normal cell has been stabilized.
