Latest Patents
One of Ralph Heron's latest patents is focused on the enhancement of input/output for non-source-synchronous interfaces. This invention presents an interface designed for devices whose core circuitry operates in one voltage domain while exchanging signals with another device, or 'host', in a different voltage domain. A concrete example of this situation is a memory card, where the internal circuitry uses one voltage range for its core operating voltages but communicates with a host using a different input/output voltage range. The interface receives data signals from the device at its core operating voltage domain, individually level shifts these to the input/output voltage domain, and combines them into a double data rate (DDR) signal for transfer to the host device.
Another significant patent by Ralph Heron extends drive capability in integrated circuits utilizing programmable-voltage output circuits. This integrated circuit (IC) includes an output driver circuit portion that can be electrically configured to operate in either a first mode or a second mode, depending on the condition of the IC, such as supply voltage indication. The configuration interface circuit portion allows for selective overriding of the configuration input to adjust the output driver circuit's operation based on a drive strength control input.
