Latest Patents

One of Jung Hwan Choi's latest patents is titled "Input receiver circuits selectively connected to input/output pad based on operation mode." This invention describes a method of operating an input/output interface that includes selecting one of several output driver circuits according to a mode selection signal. The data signal is then outputted using the selected output driver circuit. Additionally, the method generates a mode selection signal based on a received command signal, controlling an on-die termination (ODT) circuit according to the mode selection signal.

Another significant patent is for a "Semiconductor memory with dual quadrature corrected duty cycle clock outputs." This semiconductor memory device includes a data clock buffer that receives a data clock signal from a memory controller and outputs a pair of differential input signals. An edge delay controller adjusts the duty ratios of these signals based on a control code, resulting in a pair of corrected clock signals. The invention further includes circuits that generate output clock signals with different phases and a quadrature error correction circuit that detects duty errors.
