Technique for calibrating electronic devices
United States Patent 7,149,856
Garlepp, et al. December 12, 2006
Method and apparatus for adjusting the performance of a synchronous memory system
Abstract
A method and apparatus for adjusting the performance of a memory system is provided. A memory control device comprises a master device including a frequency detector, a memory channel, and a memory device coupled to the master device via the memory channel. The memory device includes a decoder designed to receive a control signal from the master device. A clock recovery and alignment circuit receives the control signal from the decoder and adjusts the operating frequency of the memory device in response to the control signal.

Technique for calibrating electronic devices
Abstract
A technique for calibrating a second electronic device using a first electronic device having a reference characteristic is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for calibrating a second electronic device using a first electronic device, wherein the first electronic device has a reference characteristic, wherein the second electronic device has an adjustable element, and wherein the first electronic device and the second electronic device are interconnected via one or more signal lines. The method comprises generating a first value based at least in part upon the reference characteristic, and providing the first value to the second electronic device via one of the one or more signal lines. The method also comprises generating a second value, based at least in part upon the first value, using the adjustable element. The method further comprises comparing the second value to the first value, and adjusting the adjustable element so as to modify the second value until the second value substantially matches the first value.
