Abstract
A method and system sorts manufactured integrated circuit devices by evaluating performance characteristics of the manufactured integrated circuit devices. All of the integrated circuit devices are manufactured using an identical design, and differences in the performance characteristics among the integrated circuit devices occurs because of variations including manufacturing line variations. The integrated circuit devices are sorted into groups according to the performance characteristics and are utilized in different computing devices depending upon individual performance requirements of the computing devices.
Claims7
A method of sorting manufactured devices, said method comprising:
- evaluating performance characteristics of manufactured integrated circuit devices, wherein all of said integrated circuit devices are manufactured using an identical design, and wherein differences in said performance characteristics among said integrated circuit devices occurs because of processing variations including manufacturing line variations;
- sorting said integrated circuit devices into groups according to said performance characteristics, wherein said sorting process is performed in a predetermined order that biases more integrated circuit devices into selected groups and less integrated circuit devices into other groups;
- and
- utilizing different groups of said integrated circuit devices in different computing devices depending upon individual performance requirements of said computing devices,
- wherein said predetermined order is based on supply and demand data of said computing devices.
