Latest Patents
One of his latest patents is a voltage generator and memory device that includes a memory cell area with multiple memory cells and a peripheral circuit area designed to control these cells. The peripheral circuits are connected to the memory cells through bit lines, word lines, and select lines. This innovative design features a reference voltage generator that outputs at least one reference voltage in response to control data from a control logic. The reference voltage generator consists of a first resistor chain and a second resistor chain, both connected in series between two power nodes, along with several decoders linked to these resistor chains.
Another notable patent involves an electronic circuit that includes a charge pump for converting voltage. This circuit comprises a first switch circuit, a second switch circuit, a pumping circuit, and a main charge pump. The first switch circuit transfers a first driving voltage to a designated node based on a clock signal. The second switch circuit then transfers a second driving voltage to another node, which is based on the first driving voltage. The pumping circuit outputs a pumping voltage that corresponds to the sum of the second driving voltage and an operational level of a second clock, while the main charge pump converts the input voltage based on this pumping voltage.
