    摘要： Disclosed herein is an apparatus for producing 3D sound. The apparatus includes a determination unit, a mono sound spreading unit, a stereo sound spreading unit, a selection unit, and a 3D sound accelerator. The determination unit receives a source sound file and determines whether the source sound file is mono or stereo. The mono sound spreading unit converts the source sound into pseudo-stereo sound and performs sound spreading on the pseudo-stereo sound, if the source sound is determined to be mono. The stereo sound spreading unit performs sound spreading on the source sound, if the source sound is determined to be stereo. The selection unit receives the output of the mono sound spreading unit or stereo sound spreading unit, and transfers the output to headphones if the headphone reproduction has been selected. The 3D sound accelerator receives the output from the selection unit if speaker reproduction has been selected, removes crosstalk from the output, and transfers the crosstalk-free output to speakers.

    摘要： A multiprocessor system includes first and second processors and a multi-path accessible semiconductor memory device including a shared memory area and a pseudo operation execution unit. The shared memory area is accessible by the first and second processors according to a page open policy. The pseudo operation execution unit responds to a virtual active command from one of the first and second processors to close a last-opened page. The virtual active command is generated with a row address not corresponding to any row of the shared memory area. For example, bit-lines of a last accessed row are pre-charged for closing the last-opened page.

    摘要： In a packet addressing method, one or more memory blocks are selected from a plurality of memory blocks and one or more data I/O pads are selected from a plurality of data I/O pads via which data input or output to/from the selected memory blocks are loaded, memory cell data output from the selected memory blocks are sequentially output to the selected data I/O pads, and data input to the selected data I/O pads are sequentially input to the selected memory blocks, so that read and write operations are independently accomplished in each of data I/O pads. The data I/O width can be adjusted according to the word length which is selectively set up, and power consumption can be reduced due to partial activation of the memory block.

    摘要： Disclosed herein is a sense amplifier circuit which includes a first, a second and a third similar load transistors. The first and second load transistors supply a dummy data line with a current of the same amount to one another. Acting in a current mirror configuration, the third load transistor supplies a data line with a current equaling the total current supplied by the first and second load transistors. A dummy memory cell is composed of the same transistor as an on-state memory cell. According to this sense amplifier structure, it is very easy to obtain a dummy cell current which has an intermediate value consistently between an on cell current and an off cell current of the memory cell, which are supplied from the third load transistor to the data line. The improved intermediate value yields a reliable readout of the memory cell.
