Abstract: There are provided a memory system and an operating method thereof. A memory system includes: a plurality of storage regions, each including a plurality of memory cells; and a controller configured to provide a plurality of read retry sets, determine an applying order of the plurality of read retry sets based on characteristics of a read error occurred in a first storage region among the plurality of storage regions, and apply at least one of the read retry sets, based on the applying order, for a read retry operation performed on the first storage region.

Abstract: The present invention provides a composition containing, as active ingredients, Panax ginseng, Adenophora triphylla, Wolfiporia extensa, Rehmannia glutinosa, and Mel for an antitussive, expectorant, or anti-inflammatory action, and a composition for preventing, alleviating, or treating a respiratory disease. The present invention provides a compositions having excellent effects compared with an existing antitussive agent and expectorant agent. The compositions of the present invention are a naturally derived material and has little cytotoxicity, and thus is expected to be safely used as a medicine or food composition having antitussive, expectorant, and anti-inflammatory effects.

Abstract: An apparatus for monitoring gas flow in a semiconductor manufacturing equipment, includes an exhaust line, a flow amount measuring unit, and a controller unit having a first input electrically connected to the flow amount measuring unit and a second input having a predetermined reference value, the controller unit having the capability of comparing data in the first input to the predetermined reference value in the second input and generate a signal when the data in the first input exceed the predetermined reference value. The apparatus of the present invention may be incorporated into a gas delivery system employed in semiconductor manufacturing to detect gas leaks.
