NAND is the most common type of flash memory. At the same time, it is used in many types of storage devices, including SSDs , USB flash drives, and SD cards. NAND memory is non-volatile, which means that it stores the data even when the power is turned off.
What is the full-form of NAND?
NAND is not an acronym. Rather, this term NAND is actually short form of ” NOT AND “, which is a boolean operator and logic gate. The NAND operator produces a FALSE value only if both values are TRUE of inputs. This can also be contrasted with the NOR operator, which only produces a TRUE value if both inputs are FALSE.
NAND vs NOR Flash Memory
NAND flash memory has an integrated circuit that uses memory cells to store the data of NAND gates. NOR flash memory stores data using NOR gates. While NOR devices read data faster, they are slower in writing data and they do not store data as efficiently.
NAND devices write and erase data faster and store significantly more data together if we compare it to the same physical size than NOR devices.
Overall, NAND storage is more efficient than NOR, which is why NAND is the most popular type of flash memory. As read and write speeds improve, NAND devices become much faster than traditional hard drives. This is why, SSDs and integrated flash memory have replaced HDDs in many computers.
