Abstract
Driving methods of a nonvolatile memory device are provided. The driving method includes providing a start pulse adjusted based on a previous write operation to a resistive memory cell to write data, verifying whether the data has accurately been written using the start pulse, and executing a write operation on the resistive memory cell by an incremental one-way write method or a decremental one-way write method according to the verify result. Related nonvolatile memory devices are also provided.
