Abstract: A method is for operating a resistive memory system including a resistive memory device implemented as multi-level memory cells. The method includes setting levels of reference voltages used to determine resistance states of the multi-level memory cells, and reading data of the multi-level memory cells based on the reference voltages. A difference between the reference voltages used to determine a relatively high resistance state is greater than a difference between the reference voltages used to determine a relatively low resistance state.

Abstract: Provided are a coding/decoding method for use in a multi-level memory system. The coding method includes searching for a set of symbols that may generate a forbidden pattern that is set initially from an input data stream, and sticking at least one bit included in the searched set of the symbols that may generate the forbidden pattern so as not to generate the forbidden pattern.
