A 90-nm CMOS 1.8-V 2-Gb NAND flash memory for mass storage applications

A 1.8-V 2-Gb NAND flash memory has been successfully developed on a 90-nm CMOS STI process technology, resulting in a 141-mm/sup 2/ die size and a 0.044-/spl mu/m/sup 2/ effective cell. For the higher level integration, critical layers are patterned with KrF photolithography. The device has three no...
