Patent ID: 6904506

Claim:
A method of automatically determining a type of a memory applied in a computer system, wherein the computer system comprises a system power state signal, a voltage control circuit and at least one memory module slot to accommodate a memory, the method comprising: outputting a preset voltage to the memory; performing an operation on the memory by executing a computer implemented set of instructions; determining a type of the memory based on the result of the executed computer implemented set of instructions; outputting a control signal based on the determined type of the memory; outputting a voltage adjustment signal according to the control signal and the system power state signal; outputting a configured operation voltage to the memory according to the voltage adjustment signal; and having the system power state signal entering a low logic state when the computer system enters a STD mode, a soft off mode or a mechanical power off mode; and having the recognition apparatus receiving the system power state signal driving the voltage control circuit to output the preset voltage to the memory.
