Latest Patents

One of his latest patents is titled "Concurrent write data strobe and reference voltage calibrations." This invention discloses an apparatus designed to perform a write data strobe concurrently with a reference voltage calibration. The memory controller circuit is configured to convey a write clock signal to a memory. It includes a calibration circuit that sends a command to initiate calibration of the write clock signal and receives a calibration value from the memory after a specified time. Additionally, a delay circuit applies a delay to the write clock signal, allowing the calibration circuit to adjust the delay based on the calibration value. This innovative approach ensures that reference voltage calibration occurs simultaneously with the write clock signal calibration.

Another notable patent is "Memory subsystem calibration using substitute results." This patent describes a memory subsystem that includes a memory controller connected to a memory through multiple signal paths. The memory controller performs an initial calibration to determine eye patterns for the signal paths. During subsequent calibrations, updated eye patterns are determined for a subset of these paths, while the remaining paths are inactive. The updated patterns for the inactive paths are derived from information obtained during the initial calibration and from the active paths designated as proxies.
