NON-VOLATILE MEMORY DEVICE AND METHOD FOR CONTROLLING DUMMY WORD LINE VOLTAGE ACCORDING TO LOCATION OF SELECTED WORD LINE

摘要

PROBLEM TO BE SOLVED: To provide a non-volatile memory device.

SOLUTION: The nonvolatile memory device comprises: an array of memory cells including main memory cells connected to many word lines and dummy cells connected to at least one dummy word line; and an access circuit for receiving addresses and commands and controlling voltage of the one dummy word line by changing the voltage depending on whether a word line selected from the many word lines on the basis of the addresses is adjacent to the one dummy word line.
