CONSTITUTION: An apparatus(200) for measuring the contamination of a semiconductor wafer(208) comprises a loader(202) on which the semiconductor wafer(208) is placed. The loader(202) moves the semiconductor wafer(208) to the measuring position. An optic member(210) is positioned on the upper portion of the loader(202). The optic member(210) generates a first signal by detecting the semiconductor wafer(208). A measuring member(212) generates a second signal by measuring the contamination degree on the surface of the semiconductor wafer(208). A storing member receives the first and the second signals and stores the signals by comparison.

Abstract: PURPOSE: A semiconductor memory device is provided to realize a fast operation by minimizing a delay of a column selection signal. CONSTITUTION: The semiconductor memory device comprises: a plurality of memory cells arranged in an array(10); a plurality of direct-type sense amplifiers(13) arranged in a column of memory cells, for writing and detecting data for memory cells to be accessed; a plurality of column selection lines(CL) for selecting sense amplifiers arranged in a column comprising the accessed memory cells; a plurality of column selection lines(CL) of a write exclusive use for selecting sense amplifiers arranged in a row comprising memory cells to be accessed when memory cells are accessed to write data; and a local driving circuit(41, 42). The sense amplifiers is divided into a sense amplifier group per each row. The column selection lines for the write exclusive use includes a first selection line for selecting a sense amplifier group arranged in a row of accessed memory cells at writing data and a second selection line for selecting sense amplifiers in the selected sense amplifier group. The local driving circuit applies a selection signal to the second selection line according to a selection signal from the first selection line. The column selection lines for the write exclusive use is controlled by a signal used to control the sense amplifiers.
