Classification: CPC G | IPC G

Claim 15:
16. The method of claim 14, wherein the performing of the first check read operation includes:
transmitting, at the memory controller, a read command to the nonvolatile memory device;
performing, at the nonvolatile memory device, a read operation by using one set of read voltages 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;
terminating, at the memory controller, the first check read operation in response to determining that the error correction decoding succeeds; and
transmitting, at the memory controller, the read command and voltage information indicating a next set of read voltages among the sets of read voltages to the nonvolatile memory device in response to determining that the error correction decoding fails.
