Abstract:
A memory device includes a first termination unit coupled to a first pin for receiving a first signal having a first frequency component. The memory device also includes a second termination unit coupled to a second pin for receiving a second signal having a second frequency component higher than the first frequency component. The first termination unit is a different type from the second termination unit that provides less signal distortion than the first termination unit. For example, the first termination unit is of an open-drain type that has less power consumption, and the second termination unit is of a push-pull type that has less signal distortion.
Abstract:
In the memory module, a buffer is disposed on one of at least two circuit boards in the memory module. The buffer is for buffering signals for memory chips on at least two circuit boards in the memory module.
Abstract:
The present invention relates to novel isocoumarin derivatves inhibiting angiogenesis, a method for preparation thereof and pharmaceutical compositions comprising the said derivatives as pharmaceutically active ingredients. More particularly, the present invention relates to novel isocoumarin derivatves represented by formula (1), especially 6,8-dihydroxy-4-acetyl-isocoumarin, a method for preparing 6,8-dihydroxy-4-acetyl-isocoumarin from fungi, and pharmaceutical compositions comprising the compounds and/or 6,8-dihydroxy-4-acetyl-isocoumarin as pharmaceutically active ingredients, which would be effective for the treatment of angiogenic diseases such as cancers, rheumatoid arthritis and diabetic retinopathy.
Abstract:
A memory module includes a plurality of semiconductor memory devices mounted on a printed wiring board (PWB); longitudinal contact terminals that are for connection to a computer mother board and are arranged along at least one longitudinal edge of the PWB; and transverse contact terminals that are for connection to the computer mother board and are arranged along at least one transverse edge of the PWB. A socket for the module includes at least one longitudinal part into which the longitudinal contact terminals are inserted and at least one transverse part into which the transverse contact terminals are inserted. Each transverse socket part can be mounted on a pivot attached to the longitudinal part and rotated to engage a PWB inserted in the longitudinal part. Alternatively, each transverse part can be a flexible circuit carrier.

Aklavinone C-11 hydroxylase separated from Streptomyces sp.; a gene encoding same; an expression vector comprising said gene; a microorganism transformed with said vector; and a process for preparing novel hybrid anthracyclines by using said vector.
Abstract:
A memory system includes an error detection circuit having an error counter. When a bit error rate (BER) determined by the error counter exceeds a reference BER, the memory system reduces the BER by adjusting its operating speed or operating voltage, re-performing data training or impedance matching, or by adjusting a data swing width. Accordingly, a method of controlling a bit error rate may be performed, and a system hang is prevented.
Abstract:
Disclosed herein are an HIF-1 inhibitor, a method for the preparation thereof, and a pharmaceutical composition comprising the same as an active ingredient. The HIF-1 inhibitor shows anticancer activity thanks to the inhibition activity against HIF-1, a transcription factor which plays an important role in the growth and metastasis of cancer, but not to general cytotoxicity. Thus, the HIF-inhibitor and a pharmaceutically acceptable salt thereof can be used as a therapeutic for various cancers such as liver cancer; stomach cancer and breast cancer. Also, the compound having inhibition activity against HIF-1 is useful in the treatment of diabetic retinopathy and arthritis, which are aggravated by HIF-1-mediated VEGF expression.
Abstract:
Disclosed is a composition for the prevention and treatment of metabolic diseases, which comprises a benzazole derivative as an active ingredient. The benzazole derivative has inhibitory activity against DGAT (diacylglycerol acyltransferase), which causes metabolic diseases such as obesity and diabetes in the process of lipid metabolism. With the ability to effectively control lipid metabolism and energy metabolism, thus, the composition is useful in the prevention and treatment of metabolic diseases, such as obesity and diabetes.
