Abstract
Aspects of the disclosure provide an integrated circuit (IC) that is configured to have an increased yield. The IC includes a memory element configured to store a specific value determined based on a characteristic of the IC, and a controller configured to control an input regulator based on the specific value of the IC. The input regulator is operative to provide a regulated input to the IC during operation, such that the IC performance satisfies performance requirement.
Claims25
An integrated circuit (IC), comprising:
- a memory element configured to store one or more specific values indicative of a lower voltage limit determined based on a speed attribute of the IC, and an upper voltage limit determined based on a power consumption attribute of the IC;
