NONVOLITILE MEMORY DEVICE AND DATA PROCESSING METHODS THEREOF

摘要

The present invention relates to a nonvolatile memory device and a data processing method for the same. The nonvolatile memory device of the present invention comprises: a first memory cell group connected to a word line, and positioned within a first distance from a reference node; a second memory cell group connected to the word line, and positioned farther from the reference node than the first distance; a first bit line group connected to the first memory cell group; a second bit line group connected to the second memory cell group; and a control logic configured to supply pre-charge voltages of different levels to the first and second bit line groups in a read or verification read operation. The nonvolatile memory device and the data processing method of the present invention can reduce a program time by decreasing a program execution time and a number of program loops.
