Claim 16:
17. The method of claim 14, wherein the performing of the second check read operation includes:
transmitting, at the memory controller and to the nonvolatile memory device, a read command and voltage information that indicates a set of read voltages used in the first check read operation and for which the error correction succeeds;
performing, at the nonvolatile memory device, a read operation by using the set of read voltages that are used in the first check read operation and for which the error correction succeeds, from among the sets of read voltages, in response to the read command, such that data read through the read operation are transmitted to the memory controller;
performing, at the memory controller, error correction decoding on the read data; and
terminating, at the memory controller, the second check read operation in response to determining that the error correction decoding succeeds.
