Abstract
A method of performing a write operation in a nonvolatile memory device comprises storing write data in a log block used to update a data block, determining whether a write pattern stored in the log block is a sequential write pattern or a random write pattern, and selecting a new data block for storing merged data in the data block and the log block. The new data block is determined to be a single-level cell block or a multi-level cell block according to the determined write pattern.
