Abstract

Integrated circuits such as programmable logic device integrated circuits are provided with adjustable configuration random-access-memory cell power supply circuitry. The adjustable configuration random-access-memory cell power supply circuitry powers configuration random-access-memory cells on an integrated circuit. During operation of the integrated circuit, the configuration random-access-memory cells provide static output signals that turn on and off associated pass transistors. The adjustable power supply circuitry can be configured to produce different power supply voltages on different portions of an integrated circuit. The different power supply voltages accommodate circuit design constraints while minimizing power consumption due to pass transistor leakage.
