Abstract
A read method of a nonvolatile memory device includes reading data from a selected memory area of the nonvolatile memory device according to a first read voltage; detecting and correcting an error of the read data; and deciding a second read voltage for reading the selected memory area when an error of the read data is uncorrectable. The second read voltage is decided according to either the number of logical 0s or 1s included in the read data, or a ratio of logical 1s to logical 0s in the read data.
