Patent number: 7668011Abstract: Provided herein is a serial flash memory device and precharging method thereof in which a single local bit-line data is sensed in synchronization with a clock. The method includes precharging two or more local bit-lines in synchronization with a first clock; and disprecharging one of the two local bit-lines in synchronization with a second clock and sensing and amplifying data of the other local bit-line. Accordingly, two precharged local bit-lines are not adjacent to each other, thereby eliminating a coupling noise effect. In addition, the time for performing the precharging operation and the sensing operation is easily secured, compared to the prior precharging method in which corresponding local bit-lines are precharged at every clock.Type: GrantFiled: September 11, 2006Date of Patent: February 23, 2010Assignee: Excel Semiconductor Inc.Inventors: Hun Woo Kye, Jong Bae Jeong, Seung Duck Kim, Sang Yong Lee, Ki Won Kwon, Seung Keun Lee

Patent number: 7483364Abstract: The present invention relates to a method and apparatus for detecting STBC-OFDM signals in time-variant channels. The method includes a step of demodulating STBC-OFDM modulation signals into OFDM reception symbols using Fast Fourier Transform (FFT); a step of estimating a frequency response for each sub-channel; an STBC decoding step of calculating decision variables determining the A transmit data symbols that are transmitted during the B OFDM symbol periods for each sub-channel; and a step of determining the transmit data symbols based on the decision variables calculated at the STBC decoding step. In this case, the decision variables are calculated using a linear equation that allows a squared Euclidean distance from OFDM reception symbols, which are demodulated during the B symbol periods, to have a local minimum for each decision variable when the STBC encoding and the frequency responses estimated during the B OFDM symbol periods are applied.Type: GrantFiled: May 6, 2005Date of Patent: January 27, 2009Assignee: Korea Electronics Technology InstituteInventors: Won Gi Jeon, Jeong Wook Seo, Jung Wook Wee, Ki Won Kwon, Jong Ho Paik, Dong Sun Kim
