Latest Patents

Lee's latest patents include a "Computing system performing duty cycle adjuster training and duty cycle adjuster training method thereof." This patent describes a training method for a memory device that adjusts the eye window of a data signal in response to a duty cycle adjuster (DCA). The method involves performing a first training operation that selects a DCA code corresponding to an internal clock signal with a specific phase difference. Additionally, a second training operation selects DCA codes corresponding to other internal clock signals with different phase differences. The eye window size of the data signal is measured in units of intervals during these operations.

Another significant patent is the "Memory system performing hierarchical duty cycle adjuster training and duty cycle adjuster training method thereof." This method outlines a training process for a memory device, where scores for various DCA code combinations are calculated based on the eye window size of a data signal. In cases of ties among scores, a DCA code combination is selected based on specific minimum values of the data signal.
