Abstract: A control circuit, a chipset and a method capable of saving the terminal resistors on a motherboard. Through the determination of connection of a pull-up enable line to a first voltage source Vdd via a resistor, an equivalent resistance is set between the source terminal and the drain terminal of a field effect transistor. The equivalent resistance is almost identical to the terminal resistor and hence can replace the resistor on the motherboard. When the pull-up enable line is connected to the first voltage source Vdd via a resistor, an equivalent resistance of about 45-60&OHgr; is established between the source and drain terminal of the field effect transistor. The equivalent resistance is connected in parallel with an input/output pad and a second voltage source Vtt to replace the original externally connected terminal resistor rt2 at the other end of the bus. If the pull-up enable line is not connected to a first voltage source Vdd via a resistor, the field effect transistor is cut off and an infinite equivalent resistance is created between the source and the drain terminal. The infinite resistance is connected in parallel between the input/output pad and the second voltage source Vtt. The infinite equivalent resistance has little effect on any externally connected terminal resistor rt2 at the other end of the bus. Hence, through enabling or disabling the pull-up enable line, manufacturers are free to choose whether to save output power to the terminal resistor rt2 at the other end of the bus or not.

Abstract: A bus architecture for the application of data transmission between distinct integrated circuits. The bus architecture includes at least one transmission line connecting with I/O pin of ICs for transmitting data. In a middle point of the transmission line, there is a middle resistor with a resistance value preferably equal to the characteristic impedance of the transmission line. In addition, there are internal pull-up resistors within the ICs, which has a first end coupled to the I/O pin and a second end coupled to the voltage source. Each pull-up resistor has a resistance value higher than the characteristic impedance of the transmission line, for example, 2 or 3 times of the characteristic impedance, for suppressing the rising edge ringback.

Abstract: An input/output (I/O) buffer with reduced ring-back effect is provided. This I/O buffer is designed for a data transmission bus, such as a GTL+bus, for the transmission of a high-frequency and low-swing data signal. This I/O buffer is designed for the purpose of reducing the undesirable ring-back effect in the I/O buffer. The I/O buffer is characterized by the provision of a variable-resistance device that is connected between the system voltage and the input end of the I/O buffer. The system voltage is set to be equal in magnitude to the high-voltage logic state of the data signal received by the I/O buffer from the data transmission bus. When the input data signal is higher in magnitude than a preset reference voltage, i.e., at the high-voltage logic state, the variable-resistance device is switched to a low resistance value; on the other hand, when the data signal is lower in magnitude than the reference voltage, the variable-resistance device is switched to a near-infinity resistance value. In both cases, no current will flow through the variable-resistance device. This feature can help reduce the ring-back effect in the I/O buffer and also allows the benefits of low power consumption and reduced layout area on the circuit board as compared to the prior art.

Abstract: An installation inside a memory slot for providing a constant loading to an external signaling line with or without the insertion of a memory module into a memory slot. The installation operates by supplying a load element whose loading effect is roughly equivalent to the loading effect of a memory module when no memory module is plugged, and disconnecting the load element internally when a memory module is plugged into the memory slot. Hence, a constant loading is provided to the external signaling line no matter a memory module is plugged or not, and so signal quality and integrity of the signaling line can be maintained.

Abstract: A system can produce a suitable voltage for powering the memory modules plugged into the memory module slots of a motherboard. A power-good signal is issued when the motherboard is powered up. A power safety device on the motherboard then issues a 2.5V to the memory module slot. If DDR DRAM type of memory modules are not detected after a while, the power safety device will turn off the 2,5V supply and provide a 3.3V, which is suitable for SDRAM type memory modules.This invention avoids sending a 3.3V to DDR DRAM modules, thereby burning the memory chip. The presence of DDR DRAM modules can be detected by a general-purpose purpose input/output port through accessing the recorded data in the EEPROM of the memory module. Alternatively, memory module type can be determined by sending out a low-current pulse signal to the memory module slot. Hence, a suitable voltage source is automatically provided to power the memory modules in the slots.

The eyesight correction lens can be positioned on the lens of eyeglasses so that a person with poor eyesight can not only protect his eyes but also see things clearly through the seeing region of the eyesight correction lenses. Since the seeing region of the eyesight correction lens does not contact with the lens of the eyeglasses, no air bubbles will be produced therebetween and hence things can be seen clearly through them. The eyesight correction lens of this invention can be combined on the lens of different eyeglasses for use and also can be removed from the eyeglasses when a user need not see things at a short distance, convenient in use.
