Latest Patent Applications

Yeonwook Jung has filed several notable patent applications. One of his applications is titled "MEMORY DEVICE, STORAGE AREA OF THE SAME, AND OPERATING METHOD OF MEMORY DEVICE." This invention describes a memory device that performs ZQ calibration by calibrating the voltage level of a data signal. The device includes a memory controller that generates the data signal, multiple channels for transmitting the data signal, and several storage areas that receive the data signal. Each storage area is equipped with an input pin for the data signal and a loop circuit that compares the voltage level of the data signal with a preset reference voltage level. Based on the comparison, the voltage level is calibrated to maintain a specific difference from the reference voltage.

Another application is "INTERFACE CIRCUITS, NON-VOLATILE MEMORY DEVICES, AND MEMORY CONTROLLERS HAVING ENHANCED OUTPUT DRIVERS THEREIN." This invention features an output driver that includes a selection circuit to output either a first pull-up driving signal or a pulse signal based on a control signal. It also incorporates a first pull-up driver circuit that provides a first supply voltage to a data pin and a second pull-up driver circuit that supplies a second voltage level. Additionally, it includes a capacitance optimization circuit to adjust the capacitance of a decoupling capacitor.
