    摘要: A circuit and a method for aligning transmitted data by adjusting transmission timing for a plurality of lanes. The method includes utilizing different initial values to reset a count value corresponding to a lane when a plurality of COM symbols are detected on the lane, utilizing an increment value to increase the count value corresponding to the lane when a COM symbol is not detected on the lane, and utilizing a plurality of count values corresponding to the lanes to align transmitted data of the lanes when a COM symbol is not detected on the lanes within a predetermined period of time.

    摘要: In a power management method of a computer system, the CPU asserts a clock-suspending grant cycle in response to a clock-suspending signal issued by the south bridge chip, and the south bridge chip issues the clock-suspending signal in response to a data write cycle asserted by the CPU. The clock-suspending grant cycle is to be transmitted to the south bridge chip via the north bridge chip when the CPU is ready to enter a power-saving mode. The north bridge chip performs a first power management operation of the peripheral device in response to the clock-suspending grant cycle. The south bridge chip performs a second power management operation of the computer system in response to the clock-suspending grant cycle.

    摘要: The present invention is related to a circuit of SRAM with current-mode write-circuits. The current-mode write-operation is through the equalization technique in advance to equalize the potential in the memory cell by using the equalization transistor. After the equalization operation, the current conveyor should pass the differential current of data into the memory cell in order to make the differential current to pull out the differential voltage through the memory cell's strong positive feedback. The present invention has seven transistors in the memory cell that is different from the conventional memory cell with six transistors. Besides, the size of each transistor can also be different from the conventional design.

    摘要: A built-in self test circuit includes a pattern generator, an elastic buffer, a symbol detector, and a comparison unit. A pattern generator generates a first test pattern to test a port under test and then a result pattern is gotten and stored in the elastic buffer. The symbol detector detects if a starting symbol exists in the test result pattern. If it exists, a second test pattern is generated to be compared with the test result pattern. As a result, a reliability of data transmission of the port under test is determined.
