NONVOLATILE MEMORY DEVICE AND METHOD FOR OPERATING THE SAME

摘要

PURPOSE: A nonvolatile memory device and a method for operating the same are provided to execute a program at each layer through a common source line. CONSTITUTION: A memory cell array(10) comprises a plurality of memory cell array layers. The memory cell array layer comprises a plurality of memory blocks(BLK0-BLKn). A layer decoder(20) selects a cell array layer from a memory cell array of a three dimensional structure according to address information. A row decoder(30) selects a memory block of the memory cell array according to the address information. The row decoder selects a word line of the selected memory block. A page buffer(40) temporarily stores data which is stored in the memory cell in an operation mode. The page buffer senses the data stored in the memory cells.
