Title: Innovations of Chung Shan Kuo

Introduction

Chung Shan Kuo is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor memory technology. With a total of 3 patents, his work has advanced the capabilities of flash memory devices.

Latest Patents

One of his latest patents is for a flash memory device and associated charge pump circuit. This invention includes a charge pump circuit that comprises a first booster set, a second booster group, and a detecting circuit. The first booster set receives a supply voltage and generates a first output voltage. The detecting circuit generates a detecting signal based on the voltage level of the first output voltage. The second booster group also receives the supply voltage and generates either the first output voltage or a second output voltage according to the detecting signal. This group consists of multiple booster sets connected in parallel, with each booster set containing several charge pump stages and switch units. The number of serially-connected charge pump stages is controlled by the switch units based on the stable voltage levels of the first and second output voltages.

Another significant patent is a programming method for nonvolatile semiconductor memory devices. This method involves programming a plurality of memory cells by sequentially performing divide-by-2 operations. After each operation, reduced groups of memory cells are generated. The memory cells of each reduced group are then programmed sequentially. A final group is created after the last divide-by-2 operation, and the memory cells of this group are programmed and verified for completeness.
