    Abstract— Flash memory is a nonvolatile computer storage de- vice which consists of blocks of cells. Flash memories have become the main type of non- volatile memories. They are widely used in mobile, embedded and mass- storage devices. Flash memories store data in. What is ECC Error Correcting Code in Flash. Because of the inherently unreliable nature of NAND memory, the stored data in NAND Flash may not hold its correct values. As the quantity of bits influenced by this statistically small and very. · To improve the reliability of Triple- Level Cell ( TLC) NAND flash memory, Advanced Error Prediction ( AEP) low- density parity- check ( LDPC) ECC with Error Dis.
