Title: Innovations of Wen Chiao Ho
Introduction
Wen Chiao Ho is a prominent inventor based in Tainan, Taiwan. He has made significant contributions to the field of memory technology, particularly in multi-level cell (MLC) memory applications. With a total of six patents to his name, his work has advanced the understanding and functionality of non-volatile memory systems.
Latest Patents
One of his latest patents is titled "Parallel threshold voltage margin search for MLC memory application." This invention outlines a method for determining read voltage margins in a memory array by comparing as-read sum codes generated from data read from the memory array with expected sum codes. The read voltage (Vt) is adjusted, and the as-read sum codes are compared to the expected sum codes to identify the Vt ranges that yield matching sum codes. This method allows for the determination of multiple read voltage margins in a parallel manner as Vt is stepped across its range.
Another notable patent is "Multi-level-cell programming methods of non-volatile memories." This invention presents a novel approach to altering the sequence of multi-level-cell programming in a multi-bit-cell of a nitride trapping memory cell. It aims to reduce or eliminate voltage threshold shifts between program steps while avoiding the suppression of the read window duration caused by complementary bit disturbance. The patent describes two embodiments for programming the multi-level cell in a multi-bit-cell with four bits, ensuring efficient programming without compromising performance.
