An objective of the present invention is to provide compounds that exhibit strong MEK-inhibiting activity and are stable in vivo and soluble in water, which can be used as preventive or therapeutic agents for proliferative diseases. The column selecting circuit includes a plurality of CMOS transmission gates, each CMOS transmission gate including an NMOS transistor connected between one bit line of a bit line pair and a sense bit line of a sense bit line pair, and a PMOS transistor connected between the one bit line and one of the write bit lines of a write bit line pair. Hereby a marking with improved security for avoiding reading errors which ensures a mandatory visual inspection of content is obtained. In order to avoid tensile forces from arising in the arrangement, or as a result of individual ferrules becoming interconnected by an applied adhesive, trenches, barriers, or also coatings are provided between the individual ferrules.
