Abstract: A memory device includes a non-volatile memory core that includes a memory cell array and a page buffer configured to store data to be programmed in the memory cell array. The device also includes a test data input buffer configured to receive test data from an external source, and control circuit that controls the non-volatile memory core and the test data input buffer. The control circuit is configured to load test data from the test data buffer to the page buffer, to program the loaded test data in the page buffer in the memory cell array, and to retain the test data in the page buffer for subsequent programming of the memory cell array. The device may further include a test data output buffer configured to receive data read from the memory cell array, and the control circuit may be operative to convey the read data from the test data output buffer to an external recipient.

Abstract: Provided is a method of storing a substrate having an active group or a probe molecule immobilized thereon. The method includes attaching a UV film to a surface of the substrate having the active group or probe immobilized thereon; and exposing the UV film to UV light, wherein the UV film comprises a UV-permeable base film and a pressure sensitive adhesive layer formed on a surface of the UV-permeable base film to immobilize the substrate, and when the pressure sensitive adhesive layer is exposed to the UV light, its adhesive force decreases.

Abstract: A microarray substrate having a patterned thin layer on a substrate is provided. In the microarray substrate, the substrate has a reflectance different from that of a material of the thin layer, and the patterned thin layer includes a spot region having a thickness at which constructive interference occurs between a first reflected light of irradiated excitation light reflected from the substrate and a second reflected light of irradiated excitation light reflected from the thin layer and a background region having a thickness at which destructive interference occurs between the first reflected light of irradiated excitation light reflected from the substrate and the second reflected light of irradiated excitation light reflected from the thin layer.

Abstract: Provided are a method of producing a substrate having a patterned organosilane layer and a method of using the substrate having the patterned organosilane layer. The method of producing the substrate having the patterned organosilane layer, includes: coating organosilane on a substrate to obtain an organosilane layer; coating a photoresist material on the organosilane layer; exposing the photoresist material to light through a mask to obtain a patterned surface on the photoresist material; developing an exposed or unexposed region of the photoresist material using a developer; and wet etching a portion of the organosilane layer in the region from which the photoresist material has been removed, using a HF-containing solution as an etchant.

Abstract: A NAND-type flash memory device including a memory cell array having a plurality of memory blocks is provided.

Abstract: Provided is a method for immobilizing a biomolecule on a solid substrate. The method includes coating the solid substrate with silane anhydride to introduce an anhydride functional group onto a surface of the solid substrate; obtaining a carboxyl group from the anhydride functional group by hydrolysis; reacting the carboxyl group with carbodiimide and succinimide to activate the carboxyl group; and contacting the biomolecule with the solid substrate having the activated carboxyl group on its surface to immobilize the biomolecule on the solid substrate.
