US 2007/0192638 A1 · Controlled power sequencing for independent logic circuits

Abstract

Embodiments of the invention address deficiencies of the art in respect to power sequencing, and provide a method, system and computer program product for supporting coupling with independent logic circuits. In one embodiment of the invention, a computer system supporting coupling with independent logic circuits may include an independent logic circuit including at least one voltage regulator that regulates voltage to core logic such that voltage is transferred to the core logic upon receiving a first level of voltage. The independent logic circuit may further include an I/O driver that becomes operational upon receiving a highest level of voltage higher than the first level of voltage. The computer system may further include a voltage ramp for transferring voltage to the independent logic circuit at the first level voltage for a predetermined period of time and subsequently at the highest level of voltage.
