ABSTRACT:
A protection circuit of the memory module and method thereof are provided. The protection circuit includes: a first voltage comparing unit, which compares a reference voltage signal with a voltage level signal to output a first driving signal; a transistor switch, which is connected among the output terminal of the first voltage comparing unit and the input terminal of the second voltage comparing unit and a power end, wherein the voltage level signal and the threshold voltage signal is compared by the second voltage comparing unit so as to output a second driving signal to a logical algorithm unit, and a logical algorithm is conducted between the second driving signal and system enable signal to output a third driving signal; and a soft start enable unit for receiving the third driving signal so as to enable a soft start process.
