NAND

NOT AND

A type of logic gate that performs a NOT-AND operation. The output of a NAND gate is the inverse or complement of the logical conjunction of its inputs. In simpler terms, the output is false when all inputs are true and the output is true for any other input combination.

This type of gate is called NAND because it performs the logical operation of negating the AND operation. Like an AND gate, it has two or more inputs, but it inverts the output of the AND operation. NAND gates are widely used in digital electronics because they can be used to implement all other types of logic gates using only NAND gates, this is known as NAND-based logic.

In flash memory context, NAND flash is a type of non-volatile memory that stores data in NAND cells, grouped together to form a NAND flash memory block, it is named after the NAND logic gate because the NAND cells are organized to make use of this logic gate. The NAND flash cells store the data in the form of electric charges and unlike other types of memory, NAND flash memory erases data in blocks, this allows the storage of large amount of data in a small space, making them widely used in consumer electronics, embedded systems and storage devices.
