Latest Patents

Ki-Seok Park'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 first DCA code corresponding to a first internal clock signal with a phase difference of 180° relative to a reference internal clock signal. Additionally, a second training operation selects a second and third DCA code corresponding to internal clock signals with phase differences of 90° and 270° respectively. The eye window size of the data signal is measured in units of two unit intervals during the first operation and in units of one unit interval during the second operation.

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 that includes first to third DCA training steps. In these steps, a score for each DCA code combination is calculated based on the eye window size of a data signal. In the event of a tie among scores, a DCA code combination is selected based on the sum of the even-eye window minimum value and the odd-eye window minimum value of the data signal.
