Abstract
A feedback system capable of accommodating different memory module loading. The feedback system utilizes the signal received by the data strobe feedback pin of a control chipset to simulate or to obtain memory module loading information so that timing of the data signal and data strobe signal can be adjusted accordingly. Therefore, data can be accurately written to or read from the memory module. The embodiment of this invention includes using a variable reference voltage source and a comparator to adjust the timing of the signal to the data strobe feedback pin, using independent simulating loads circuit and specially designed memory module with simulating load, and using a data strobe signal circuit that includes complete memory module loading.
