NAND FLASH
NAND flash also uses floating-gate transistors, but they are connected in a way that resembles a NAND gate:
several transistors are connected in series, and the bit line is pulled low only if all the word lines are pulled high (above the transistors' VT).
These groups are then connected via some additional transistors to a NOR-style bit line array in the same way
that single transistors are linked in NOR flash.
