Title: The Innovative Contributions of Ping Guo
Introduction
Ping Guo is a notable inventor based in Campbell, California. He has made significant contributions to the field of flash memory technology. His innovative approach to programming methods has led to the development of a unique patent that enhances the efficiency of data storage.
Latest Patents
Ping Guo holds a patent for an "Adaptive programming method and apparatus for flash memory analog storage." This invention involves adjusting the voltage of the programming pulse based on the results of previous pulses. The method compares the expected change in the programmed value to the measured change, allowing for continuous improvement of the cell's programming model. The algorithm is termed "adaptive" because it modifies the voltage of each pulse according to the specific needs of the cell. If a cell is programming too slowly, the voltage is increased significantly to expedite the process. Conversely, if a cell is programming too quickly, the next voltage pulse is adjusted minimally or even decreased. This innovative approach utilizes a special analog circuit to determine the optimal voltage for each pulse, although digital calculations may also be employed. The speed of this programming method allows for the sampling and storage of voice signals in flash memory one cell at a time.
