Abstract
A multi-chip system in which at least one of the chips includes a performance parameter encoded thereon. After system assembly, the performance parameter can be obtained by a companion chip and used to automatically or semi-automatically fine tune the companion chip to the specific parameters of the at least one chip.
Claims20
A method comprising:
- fabricating a device including a signature file memory;
- testing the device to determine one or more performance parameters;
- storing the parameters in the signature file memory;
- and
- packaging the device.
A method of using a multi-chip integrated circuit system comprising using a signature file on one of the chips to adjust the gain of an amplifier to affect input/output impedance matching.
A method of using a multi-chip integrated circuit system comprising using a signature file on one of the chips to match a driver more accurately to a driven load.
