Latest Patents

One of Jiawei Chen's latest patents focuses on techniques to calibrate an impedance level. This invention describes methods for calibrating resistances provided by pull-up and pull-down circuits in an output driver circuit. A first reference voltage is determined and applied to set a resistance level of a pull-up circuit to a desired level. Additionally, a code for activating one or more transistors in the pull-up circuit is determined against the first reference voltage. For the pull-down circuit, a second reference voltage is set to establish a resistance level that matches the pull-up circuit. The first and second reference voltages can be represented by index values, and the codes can be stored for future use.

Another significant patent involves apparatuses and methods for compensating for process, voltage, and temperature variations in memory systems. This invention outlines systems and methods designed to mitigate variations in process, voltage, and temperature in memory circuits. A pre-driver circuit and driver circuit are associated with the memory circuit, and a reference generator provides reference signals that are insensitive to these variations. The output from the pre-driver circuit is then supplied to a driver circuit, resulting in a final driver data output with reduced noise.
