Title: Toshiaki Takeshita: Innovator in Semiconductor Technology
Introduction
Toshiaki Takeshita is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of five patents. His work focuses on improving memory cell performance and erasing methods in NAND flash memory.
Latest Patents
One of his latest patents is related to a semiconductor device and an erasing method. This innovation aims to alleviate the deterioration of a memory cell caused by ISPE. The NAND flash memory described in the patent includes a memory cell array and an erasing component that efficiently erases selected blocks of the memory cell array. The erasing component performs both a first and a second erasing verification (EV) on the selected block. If the first EV passes but the second fails, an erase pulse with the same voltage as the last application is used. Conversely, if the first EV fails, a higher voltage erase pulse is applied. Another notable patent involves a semiconductor memory apparatus that adopts a new ISPP method with a sacrificial programming pulse. This method enhances the programming of memory cells by applying a programming pulse based on the ISPP to a selected page of the memory cell array.
