Abstract: A memory device includes a plurality of memory cell transistors, a first word line, a controller, and a storage circuit. Each of the plurality of memory cell transistors stores a plurality of pieces of bit data. The first word line is connected to a plurality of first memory cell transistors in the plurality of memory cell transistors. The controller performs a loop process including repetition of a program loop including a program operation and a first verification operation. The storage circuit stores status information. The controller performs the loop process, then performs a second verification operation, and stores first status data corresponding to a result of the loop process and second status data corresponding to a result of the second verification operation in the storage circuit, in a write operation using the plurality of first memory cell transistors as targets.

Abstract: There is provided a stop for a slide fastener. A top plate and a bottom plate are linked with one another at a transversely intermediate position by an integral connecting post. The lower side of the top plate is substantially flat. The bottom plate slopes away from the connecting post to form two leg members provided with a respective end flange pointing towards the top plate, the leg members being adapted to cooperate in use with the top plate to retain fastener tapes therebetween.

Abstract: Metallic one-side teeth include an upper inclined plane declining toward the side of interlock dent portion provided between the opening edge of the interlock dent portion and the apical edge of an interlock head portion.

Abstract: Metallic one-side teeth that attain preventing of colliding contact at interlock, enhancing of rigidity against moment by horizontal pull force and construction of simple structure; and a two-way slide fastener utilizing the metallic one-side teeth. An upper inclined plane (8) declining toward the side of interlock dent portion (5) is provided between the opening edge (5a) of the interlock dent portion (5) and the apical edge (7) of an interlock head portion (3). By virtue of the upper inclined plane (8), at insertion in the interlock dent portion (5), there can be prevented any insertion of an interlock convex portion (4) as an interlock counterpart-side while making colliding contact with the interlock head portion (3). Accordingly, the sliding movement of slider for opening/closing of a two-way slide fastener can be smoothed.
