Abstract

A 5-V-only 16-Mb CMOS flash memory with sector erase mode is described. An optimized memory cell with diffusion self-aligned drain structure and channel erase are keys to achieving 5-V-only operation. By adopting this erase method and row decoders to apply negative bias, 512-word sector erase can be realized. The auto chip erase time of 4 s has been achieved by adopting 64-b simultaneous operation and improved erase sequence. The cell size is 1.7 mu m*2.0 mu m and the chip size is 6.3 mm*18.5 mm using 0.6- mu m double-layer metal triple-well CMOS technology.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
