Abstract: Semiconductor memory devices may include a write transistor including a first write gate controlling a first source/drain terminal and a second write gate controlling a channel region, and a read transistor including a memory node gate connected to the first source/drain terminal of the write transistor. The first write gate may have a first work function and the second write gate may have a second work function different from the first work function. The first source/drain terminal of the write transistor may not have a PN junction.

Abstract: A driving circuit includes a plurality of stages driven in response to a start signal. Each normal stage outputs a gate signal and a carry signal, increases an electric potential of a node in response to a previous carry signal of a previous stage, and decreases the gate signal to a first voltage in response to a carry signal from a next stage. Each stage applies a second voltage lower than the first voltage to the node in response to receipt of a carry signal from a second next stage. A first dummy stage outputs a first dummy carry signal to the last two normal stages in response to a last carry signal from the last normal stage and the start signal, and a second dummy stage outputs a second dummy carry signal to the last normal stage in response to the first dummy carry signal and the start signal.

Abstract: The present invention relates to a compressor for sucking, compressing and discharging a refrigerant gas from the external refrigerant circuit. The compressor includes: a suction muffler chamber having a suction port formed on the outer circumference of a cylinder block, which has a plurality of bores arranged in a line, and an oil storing part for storing oil, the suction port being communicated with the external refrigerant circuit; and a rear housing connected to the cylinder block to close the rear end of the cylinder block and having a suction chamber and a discharge chamber therein, the rear housing having a suction chamber communicating passage for communicating the suction chamber with the suction muffler chamber at the upstream part of the suction chamber. The compressor can effectively reduce a pressure pulsation of the suction gas and a noise due to the pressure pulsation without causing an increase of the overall length and the entire volume of the compressor, improve lubrication at the time of an initial start, and increase suction and compression efficiencies.
