    Abstract: A signal reception apparatus and method for communication systems. The signal reception apparatus for communication systems according to the present invention is applicable to communication environments in which a plurality of sub-bands having different frequency bands are sequentially used for communications. An embodiment of the invention has a multi-band index generation unit, a multi-band frequency generation unit, a multiplication unit, a correlation signal reception unit, and a buffer unit. The multi-band index generation unit generates a multi-band index corresponding to a sub-band to which a received signal is transmitted in correspondence with the multi-band index. The multiplication unit outputs a signal obtained by multiplying the received signal by the multi-band frequency. The correlation signal reception unit integrates and outputs the signal of the multiplication unit based on an integral time set in correspondence with the multi-band index. Further, the buffer unit buffers the signal of the correlation signal reception unit to be outputted at a predetermined data rate.

    Abstract: An apparatus and method for generating an intermediate frequency (IF) to be transferred to a single sideband (SSB) generator which generates carriers using one local oscillator (LO) signal and at least two IF signals that are received. A group signal is generated which includes a non-phase-shifted signal and a phase-shifted signal to a predetermined value with respect to each IF. One of the group signals is selected and transferred to the SSB generator. Accordingly, the SSB generator performs the phase shift on the LO signal alone.

    Abstract: An flash memory device includes a block of NAND cell units, each NAND cell unit in the block includes n memory cell transistors MC controlled by a plurality of n wordlines, and is connected in series between a string selection transistor SST connected to a bitline and a ground selection transistor GST. While a programming voltage Vpgm is applied to a selected wordline WL , a cutoff voltage Vss is applied to a nearby unselected wordline closer to the ground selection transistor GST to isolate a first local channel Ch1 from a second local channel Ch2. As the location i of the selected wordline WL increases close to the SST, the second channel potential Vch2 tends to increase excessively, causing errors. The excessive increase of Vch2 is prevented by modifying the voltages applied to string select lines (SSL) and/or to the bit lines (BL), or the pass voltages Vpass applied to the unselected wordlines (WL location i is equal or greater than a predetermined (stored) location number x. If incremental step pulse programming (ISPP) is implemented, the applied voltages are modified only if the ISPP loop count j is equal or greater than a predetermined (stored) critical loop number y.
