Latest Patents
Kyoung Youn Lee's latest patents include innovative designs for semiconductor devices and power supply circuits. The semiconductor device patent features a delay time adjustment circuit and an address input circuit. The delay time adjustment circuit is designed to adjust the timing of charge supply to internal nodes based on the back-bias voltage, which is responsive to a test mode signal. Additionally, it generates a bank selection signal by delaying an active signal according to the charge amounts of the internal nodes. The address input circuit, driven by the back-bias voltage, receives an address in response to the bank selection signal to produce an internal address, incorporating a second delay time that varies with the back-bias voltage.
The power supply circuit patent outlines a system for supplying an internal voltage to an output node. It includes a pull-up driver that generates the internal voltage from a power supply voltage based on comparisons with reference voltages. The circuit also features a pull-down driver for discharging the internal voltage and blocking units to manage the operation of both drivers based on the internal voltage levels.
