NON-VOLATILE MEMORY SYSTEM AND INFORMATION PROCESSING SYSTEM INCLUDING THE SAME

摘要

PURPOSE: A nonvolatile memory system and an information processing system including the same are provided to stably detect a logic value of a data signal by detecting a constant reference signal regardless of a cell property of a reference memory cell. CONSTITUTION: A plurality of main memory cells to store data are arranged in a data cell array(100). A reference cell array provides a reference signal for processing data by using a pair of first and second reference memory cells connected to an odd word line and an even word line as a reference cell. A reference cell control unit(300) selects a first reference memory cell and a second reference memory cell by interlocking with a signal applied to the data cell array.
