Abstract
A nonvolatile memory device comprises a nonvolatile memory chip comprising a static latch, first and second dynamic latches that receive the data stored in the static latch through a floating node, and a memory cell configured to store multi-bit data. The nonvolatile memory device performs a refresh operation on the first dynamic latch where externally supplied first single bit data is stored in the first dynamic latch, performs a refresh operation on the second dynamic latch where externally supplied second single bit data is stored in the second dynamic latch, and programs the memory cell using the data stored in the first and second dynamic latches after the first and second single bit data are stored in the respective first and second dynamic latches.
