A new floating gate cell structure with a silicon-nitride cap layer for sub-20 nm NAND flash memory

A new cell structure of NAND memory devices, which employs an additional nitride layer between the top of a floating gate (FG) and inter-poly dielectrics (IPD), is devised to lesson a high electric field on the FG top edges during program. The cell structure is proved to be promising in sub-20 nm NA...
