Abstract: The present invention relates to a trypsin-free cell stamp system and a use thereof. According to the present invention, an increase in the passage number of stem cells can be prevented compared with conventional methods of isolating cells from a cell culture dish, while providing a support, which is an essential condition of cell growth, by introducing the trypsin-free cell stamp system, and cells can be continuously supplied for a polymer-based fiber support without an additional subculture process since the empty space of a cell culture dish is filled as times passes. In addition, the artificial effects on cells can be minimized since the cells migrate to a polymer-based nano/micro-fiber support without other external stimulation, and thus the potency of stem cells is increased, thereby inducing more effective differentiation, such that the present invention, as a cell therapeutic agent, can be utilized in general fields of regenerative medicine and tissue engineering.

Abstract: A semiconductor memory device includes a plurality of sub-wordlines, a plurality of sub-wordlines corresponding a redundancy main wordline, a plurality of redundancy memory cells each being coupled to each of the redundancy sub-wordlines, and a redundancy control circuit for disabling the main wordline selector when among the sub-wordlines, a sub-wordline to which a defective memory cell is coupled is addressed, and for controlling the sub-wordline to be replaced by the redundancy main wordline. The number of the redundancy sub-wordlines coupled to the redundancy main wordline is smaller than the number of the sub-wordlines coupled to the main wordline. Therefore, when among the sub-wordlines coupled to the main wordline, a sub-wordline to which a normal main memory cell is coupled is addressed, the main wordline selector is enabled to improve a redundancy flexibility and reduce a circuit area.
