A chemical supply system, includes: a chemical container receiving station configured to receive a chemical container, inspect chemical information of the chemical container and confirm the chemical information; a temporary storage configured to store the chemical container; a chemical supply device configured to supply a chemical in the chemical container to a place of use of the chemical; a first robot configured to transport the chemical container for which the chemical information is confirmed from the chemical container receiving station; and a second robot configured to carry the chemical container transported by the first robot into the chemical supply device.

Chemical supply system

Provided is a method for programming a nonvolatile memory device. The nonvolatile memory device includes a local word line to divide a memory cell string into a first area including a selected word line and a second area not including the selected word line. In the method, word lines of the first area are driven by a first pass voltage and word lines of the second area driven by a second pass voltage higher than the first pass voltage. A cell transistor corresponding to the local word line is turned off after the first pass voltage and the second pass voltage are applied. The selected word line is driven by a program voltage after the cell transistor is turned off.

Methods for programming nonvolatile memory devices

A nonvolatile memory device includes; a memory cell array configured into a plurality of memory blocks, a decoder connected to the plurality of memory blocks via a word line, a page buffer connected to the plurality of memory blocks via a bit line, and control logic configured to define a control voltage applied to at least one of the word line and the bit line during a program/verify operation in accordance with a location of each one of the plurality of memory blocks within the memory cell array.
