摘要： A power surge detection device is disclosed to investigate if there is any power surge occurring to a main processor in a computer system. When the width or frequency of power surges detected jeopardize the normal operation of the computer system, an alerting signal, for example, an interrupt signal or a power management signal, is sent to the main processor to intervene in the normal operation of the computer system so as to avoid the power instability period.

摘要： A voltage-switching regulator with built-in voltage-switching module is provided, which is capable of supplying a terminal voltage to a memory unit operating under DDR (DRAM of Double Rate) mode. The voltage-switching regulator is implemented as a single IC chip with a built-in voltage-switching module, and is capable of generating a terminal voltage in response to an input reference voltage and transferring the terminal voltage via a transmission logic line to the memory unit operating under DDR mode. The terminal voltage is pulled up when the voltage-switching module supplies a drive current and is pulled down when the voltage-switching module supplies a sink current. This allows the memory unit to be operated under DDR mode.
