Patent number: 9104533Abstract: A voltage and timing calibration method used in a memory system. A memory controller adjusts timing and voltages of the controller and voltages of a memory buffer according to data returned by the buffer based on timing and voltages at a memory controller side of the buffer, to calibrate timing and voltages between the controller and controller side. According to data read by the buffer from a memory chip unit on the basis of timing and voltages at a memory chip side of the buffer, the controller adjusts the timing and voltage at the chip side and the voltage of the chip unit; or the buffer adjusts the timing and voltage at the chip side and the voltage of the chip unit, to calibrate the timing and voltage between the chip side and chip unit. Therefore, hardware resources of the buffer can be saved and the circuit can be simplified.Type: GrantFiled: December 14, 2012Date of Patent: August 11, 2015Assignee: MONTAGE TECHNOLOGY (SHANGHAI) CO., LTD.Inventors: Chunyi Li, Qingjiang Ma
