Witryna1 lut 2024 · The disturbance mechanism of dummy cell during memory cell cycling has been investigated in 3D NAND flash. Edge dummy cell (DMY) threshold voltage increasing was observed during cell program and erase cycling, which leads to a reduced string current and read failure. Witryna与主流的NAND Flash相比,NOR Flash容量密度小、写入速度慢、擦除速度慢、价格高,但是NOR Flash由于其地址线和数据线分开的特性,不必再把代码读到系统RAM中,应用程序可以直接在NOR上运行(XIP,eXecute In Place),且NOR Flash还具备更快的读取速度、更强的可靠性和更 ...
