20120112849 | DATA TRANSMISSION SYSTEM AND SEMICONDUCTOR CIRCUIT - A data transmission system is provided in which it is possible to perform both of suppressing the degrading of the slew rate and suppressing the ringing even if load capacitance of an input buffer is changed. | 05-10-2012 |
20120262885 | SIGNAL TRANSFER CIRCUIT - Provided is a signal transfer circuit which uses a low cost circuit board with a high packing density but is capable of reducing a crosstalk noise between signal lines and also reducing a reflection noise due to a stub. A signal transfer circuit of the present invention is configured such that lead terminals of electronic components and through-hole vias are connected to each other by surface wirings, respectively, to allow no branching from the middle of the through-hole vias. Further, first wirings connecting a first electronic component are each arranged between a corresponding pair of second wirings connecting a second electronic component, and signals are transmitted through the first wirings and the second wirings by interleaved transmission. | 10-18-2012 |
20130207234 | SEMICONDUCTOR APPARATUS, SIGNAL TRANSMISSION SYSTEM AND SIGNAL TRANSMISSION METHOD - A slew rate of a signal transmitted between a semiconductor device having a small load capacitance and a semiconductor device having a large load capacitance is improved. When a signal is transmitted to the semiconductor device (for example, a memory device) having the large load capacitance, pre-emphasis is performed, and when a signal is transmitted to the semiconductor device (for example, a memory controller) having the small load capacitance, pre-emphasis is not performed or is slightly performed. By this, when the signal is transmitted to the memory device, blunting in signal rising due to the load capacitance is suppressed, and when the signal is transmitted to the memory controller, ringing due to the reflection of the signal is suppressed, and the slew rate of the data transmission is improved. | 08-15-2013 |
20130307582 | SEMICONDUCTOR DEVICE - To suppress power consumption and enhance signal quality as compared with the case where first and second semiconductor elements are terminated only by on-chip input termination resistor circuits. A first semiconductor element with a switching function and a second semiconductor element with a switching function are connected to each other with a substrate interconnection, and a resistor element is connected in parallel with the substrate interconnection. The resistor element is placed at an arbitrary position or a branch point on the signal interconnection. | 11-21-2013 |
20140112073 | SIGNAL TRANSMISSION SYSTEM AND STORAGE SYSTEM - A signal transmission system is provided which connects a memory controller and a plurality of semiconductor memories. The signal transmission system comprises a semiconductor device arranged between the memory controller and the plurality of memories, in which: the semi-conductor device comprises a control circuit; and the control circuit receives a signal from the semiconductor memory and outputs a control signal to the memory controller in response to the signal from the semiconductor memory. | 04-24-2014 |
