摘要:
The present invention relates to a lectin protein prepared from Korean marine crab Philyra pisum, process for preparing the same and the use thereof. This protein can be used as a diagnosing agent or a carrier protein that chemically binds to various anti-cancer drugs owing to its capability that specifically recognizes N-glycolylneuraminic acid, and, in addition, used as an anti-cancer drug in view of its anti-proliferation effect.

Embodiments of the invention include a stacked board-on-chip (BOC) package having a mirroring structure and a dual inline memory module (DIMM) on which the stacked BOC package is mounted. A bottom surface of a first semiconductor chip faces a bottom surface of a second semiconductor chip. An interposer electrically connects first and second packages, respectively comprising the first and second semiconductor chips, to each other. The DIMM is obtained by electrically connecting BOC packages to each other on upper and lower substrates of a printed circuit board. Since a height of the stacked BOC packages is greater than a height of a conventional stacked BOC package, the DIMM has a minimum stub length and an optimal topology. Hence, the DIMM can have a signal with excellent fidelity by reducing a load upon a signal line, and installation or wiring of components within the DIMM 300 requires less effort.

Disclosed herein is a method of manufacturing a package substrate with a fine circuit pattern using anodic oxidation. By anodizing a metal core which is opened through a masking process, oxidation layers are formed in open areas of the metal core to insulate portions of circuit pattern from each other. Further, by electroplating portions provided between the oxidation layers with copper or filling conductive paste between the oxidation layers using a screen, a package substrate having a fine circuit pattern is achieved.

Embodiments of the present invention may include an integrated circuit module structure for a high-density mounting. An embodiment may include a wiring board, having a mounting space with a mounting length determined in a first direction and a mounting width determined in a second direction, on at least one surface thereof, and a plurality of integrated circuit packages having a package mounting combination length longer than the mounting length of the wiring board. An embodiment may also have some packages among the plurality of integrated circuit packages mounted directly on the mounting space, while other packages are mounted indirectly on the mounting space. The present embodiment may have packages that are overlapped horizontally and vertically distant from one another. Embodiments allow a plurality of chips or packages to be mounted in a limited area without changing a form factor of integrated circuit module even when integrated circuit chip or package size increases.
摘要:
A circuit for controlling an AC-timing parameter of a semiconductor memory device and method thereof are provided. The AC-timing parameter control circuit includes a delay-time-defining portion, a comparing portion, and a controlling portion. The control circuit compares the pulse width or period of an input signal to one or more different reference-widths pulses, with the reference width(s) set by the delay-time-defining portion and the reference pulses generated by the comparing portion. The controlling portion indicates whether the input signal width or period was less than or greater than each o the reference-width pulses. The control circuit output signals can be used to tailor the operation of the device based on a direct comparison of an AC-timing parameter to one or more reference values.
