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: A data receiver includes a first buffer circuit and a second buffer circuit. The first buffer circuit varies a resistance of a data path and a resistance of a reference voltage path based on a plurality of control signals, and adjusts a voltage level of an input data signal and a level of a reference voltage to generate an internal data signal and an internal reference voltage based on the varied resistance of the data path and the varied resistance of the reference voltage path. The second buffer circuit compares the internal data signal with the internal reference voltage to generate a data signal.

Abstract: Pairs of registers with reduced pins are disposed to overlap on front and back surfaces of a memory module. An input signal INS is transferred through the registers in series in a daisy chain fashion to avoid divergence of the input signal INS for preserved signal integrity. Each register buffers the input signal INS to memory banks disposed closely to sides of the register for reduced wiring area.
