Latest Patents

One of Lin's latest patents is titled "Multi-stage charge pump without threshold drop with frequency modulation between embedded mode operations." This invention features a multimode charge pump circuit that utilizes a single charge pump responsive to a set of clock signals. The clock signals are provided in two modes, each with variable frequencies based on supply potential and temperature. The circuit is designed to configure all stages in series during the first mode to produce a higher voltage output, while a subset of stages is configured in series during the second mode to generate a lower voltage output. Additionally, a precharge circuit operates as a supply node in the second mode and as a precharge/clamp in the first mode.

Another notable patent is related to a "Memory system and a voltage regulator." This regulator is designed to regulate the program voltage of a memory device. It includes an operating amplifier, a program path emulation apparatus, and a current mirror that controls the current flowing in the program path emulation apparatus. The program path emulation apparatus emulates various components of the memory device, allowing for flexibility in the predetermined current based on the program times of the memory cells.
