NAND

NAND is the most common type of flash paměť. It is used in several types of storage devices, including SSD, USB flash disky, a SD karty. NAND memory is non-volatile, meaning it retains stored data even when the power is turned off.

What does NAND stand for?

Surprisingly, NAND is not an acronym. Instead, the term is short for "NOT AND," a boolean operator and logická brána. The NAND operator produces a FALSE value only if both values of its two inputs are TRUE. It may 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 contains an integrovaný obvod that uses NAND gates to store data in memory cells. NOR flash memory stores data using NOR gates. While NOR devices read data faster, they are slower at writing data and do not store data as efficiently. NAND devices write and erase data faster and store significantly more data than NOR devices of the same physical size.

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 have improved, NAND devices have become faster than traditional pevné disky. Therefore, SSDs and integrated flash memory have replaced Pevné disky in most computers.
