Abstract: A wireless receiver receives a signal obtained by multiplexing a plurality of signals that include a synchronization signal that is spread using a non-orthogonal code not orthogonal to a code for spreading other signals other than the synchronization signal. Then, in a case when the signals other than the synchronization signal are the target signals for decoding, the wireless receiver performs despreading with respect to the received signal using the synchronization signal and estimates the signal amplitude of the non-orthogonal code. Subsequently, the wireless receiver eliminates the spread synchronization signal from the received signal using the estimated signal amplitude of the non-orthogonal code and using the synchronization signal. Eventually, the wireless receiver performs despreading and demodulation with respect to the signal having the spread synchronization signal eliminated therefrom and decodes the target signals for decoding.

Abstract: A partial area for retaining data during low power consumption mode is composed of a single first memory cell out of a plurality of memory cells connected to a bit line. An operation control circuit operates any of the memory cells selected in accordance with an address signal during normal operation mode for performing a read operation and a write operation. The operation control circuit keeps latching data retained by the first memory cell in the partial area into a sense amplifier during the low power consumption mode. This eliminates the need for a refresh operation for retaining the data in the first memory cell during the low power consumption mode. Since the data can be retained without a refresh operation, it is possible to reduce the power consumption during the low power consumption mode.

Abstract: Conductive or solder bumps are stacked between a mounted component such as a BGA device and a printed wiring substrate in a multileveled printed circuit board unit. An interposer or relay substrate is interposed between the adjacent stacked conductive bumps. The interposer substrate is made of a porous material. When any difference in the expansion is caused between the printed wiring substrate and the mounted component, one side of the interposer substrate receives a relatively smaller displacement force while the other side of the interposer substrate receives a relatively larger displacement force. A shearing stress is induced in the interposer substrate. Deformation of the porous material serves to absorb the shearing stress in the interposer substrate. The conductive bumps bonded on one side of the interposer substrate as well as the conductive bumps bonded on the other side of the interposer substrate may be relieved from a shearing stress.
