Abstract
A redundant array of inexpensive disks (RAID) system including nonvolatile memory and an operating method of the same is provided. A nonvolatile memory device implemented as a RAID and including a plurality of first memory chips, which store data chunks, and a second memory chip, in which spare memory regions are defined. A RAID controller controls RAID operations and a rebuild operation of the nonvolatile memory device. The RAID controller monitors a failure probability of each of the first memory chips, and in response to detecting a failure probability of two or more first memory chips that satisfies a predefined threshold value, a first rebuild on data stored in each of the first memory chips is performed to store the data in the second memory chip. A second rebuild on data stored in the first memory chip having the failure using data stored in the second memory chip.
