Patent ID: 8024540

Claim:
An integrated memory control method, for an interface controller coupled to a control chip through a first serial peripheral interface, coupled to a micro-processor unit through a general transmission interface, and coupled to a memory through a second serial peripheral interface to control transmitted signals between the memory and the control chip, and between the memory and the micro-processor unit, the integrated memory control method comprising: receiving a first request sent from the control chip and a second request sent from the micro-processor unit respectively for reading data from the memory; bridging the first request to the memory; sending a wait signal to the micro-processor unit; operating a frequency of a first clock signal sent from the second serial peripheral interface higher than a frequency of a second clock signal sent from the first serial peripheral interface; and varying the frequency of the second clock when time points for the second serial peripheral interface transmitting addresses correspondingly fall behind time points for the first serial peripheral interface transmitting addresses.
