摘要
An operating method of a nonvolatile memory system includes receiving a read request for at least one page from a host. Upon receiving the read request, read voltages are adjusted using a read history table to perform a first read operation in which data stored at the nonvolatile memory is read. An optimal read voltage set is detected when data read according to the first read operation includes an uncorrectable error, and a second read operation is performed in which the stored data is read based on the detected optimal read voltage set. The read history table is updated based on a reliability parameter indicating a characteristic of the nonvolatile memory, a characteristic of the data at the first or second read operation, the optimal read voltage, or the read history table.
