Title: Innovations of Chia-Shing Chen in Semiconductor Memory Technology
Introduction
Chia-Shing Chen is a prominent inventor based in Hsing Chu, Taiwan. He has made significant contributions to the field of semiconductor memory technology, holding a total of 8 patents. His work focuses on enhancing the efficiency and performance of nonvolatile memory devices.
Latest Patents
One of his latest patents is a method for fabricating an asymmetric virtual ground P-channel flash cell. This invention features a memory cell with an asymmetric source and drain connection to virtual ground bit-lines. It provides an abrupt junction suitable for band-to-band hot electron generation and a gradual junction suitable for Fowler-Nordheim tunneling on each side of the cells. The patent describes a nonvolatile semiconductor memory device comprising a row and column arrangement of the cells, where adjacent columns of cells share a single virtual ground bit line.
Another notable patent is the method for forming asymmetric flash EEPROM with a pocket to focus. This memory cell also has an asymmetric source and drain connection to virtual ground bit-lines. The design includes a main diffusion adjacent to the drain, which allows for Fowler-Nordheim tunneling erasure on the drain side of the floating gate. A pocket diffusion between the main diffusion and the source concentrates the electric field, enhancing the efficiency of programming by electron injection on the source side of the floating gate. This method results in increased floating gate memory array density and programming speed while reducing power consumption and the likelihood of a disturb condition.
