Title: Innovations of Chung Ju Chen in Memory Technology
Introduction
Chung Ju Chen is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of memory technology, holding a total of 3 patents. His work focuses on enhancing the performance and reliability of memory cells, which are crucial components in modern electronic devices.
Latest Patents
One of his latest patents is titled "Process and integrated circuit for a multilevel memory cell with an asymmetric drain." This invention introduces an asymmetric multilevel memory cell that provides an inhibited source read current. The design dramatically reduces the likelihood of cell type misread errors in memory arrays comprising multilevel cells. The fabrication method involves a source-only implant and the formation of a spacer on the drain side of the gate prior to the source/drain implant. This results in an offset region that is not controlled by the gate voltage, allowing for improved performance. The drain current at 1.5 volts is more than 3.5 times larger than the source current at the same voltage for a spacer width of 0.12 micrometers.
Another notable patent is the "Multi level mask ROM with single current path." This invention describes Mask ROMs with fixed code implantation and associated integrated circuits. The integrated circuit features an array of memory cells, including two banks separated by select lines. The use of fixed code implantation results in a single current path during the reading of a memory cell, allowing for a reduction in device size and improved topography. This design also optimizes the use of select transistors and sense amplifiers, enhancing the overall efficiency of the memory cell array.
