摘要: An input/output driver for interfacing directly with a voltage at a pad (820) which is above a supply voltage (817) for the input/output driver. This may be referred to as an “overvoltage condition.” For example, if the supply voltage is 3.3 volts, a 5-volt signal may be provided at the pad of the input/output driver. The input/output driver will tolerate this voltage level and prevent leakage current paths. This will improve the performance, reliability, and longevity of the integrated circuit. The input/output driver includes a well-bias generator (1002) for preventing leakage current paths.

摘要: A technique provides an on-chip voltage to a core portion of an integrated circuit by way of a conversion transistor. The on-chip voltage may be a reduced internal voltage, less than the VCC of the integrated circuit. In an embodiment, the layout (or physical structure) of the conversion transistor is distributed surrounding the core portion. By providing the core with a reduced voltage, the integrated circuit may interface with other integrated circuits compatible with different voltage levels.

摘要: A static, nonvolatile, and reprogrammable programmable interconnect junction cell for implementing programmable interconnect in an integrated circuit. The programmable interconnect junction (600) is programmably configured to couple or decouple a first interconnect line (210) and a second interconnect line (220). The configured state of the programmable interconnect junction is detected directly, and memory cell detection circuitry such as sense amplifiers are not needed during normal operation. Full-rail voltages may be passed from the first interconnect line and the second interconnect line.

摘要: A technique and circuitry to interface an integrated circuit to other integrated circuits in a mixed-voltage mode environment. In particular, the integrated circuit is fabricated using technology compatible with an internal supply voltage level. Externally, the integrated circuit will interface with an external supply voltage level, above the internal supply voltage level. The input and output signals to and from the integrated circuit will be compatible with the external supply level. Specifically, a level shifter (1317) or similar conversion circuit is used to convert voltages compatible with the internal supply level to be compatible with the external supply level.
