Web14 de ago. de 2024 · A NOR flash might address memory by page and then by word. NAND flash might address it by page, word and bit. Bit-level addressing suits bit-serial … WebFigure 2 shows a comparison of NAND Flash an d NOR Flash cells. NAND efficiencies are due in part to the small number of metal co ntacts in the NAND Flash string. NAND Flash cell size is much smaller than NOR Flash cell size—4F 2 compared to 10F 2—because NOR Flash cells require a separate metal contact for each cell.
