On Chip ECC for Cypress NAND Flash Devices – KBA219705

Version: **



Do Cypress NAND Flash devices have On Chip ECC?



No, our current product line, namely the S34ML-2, S34MS-2, S34ML-1, and S34MS-1 families of SLC NAND Flash, does not have On Chip ECC. The error correction code, whether it is hardware or software, is the responsibility of the host system. The NAND simply provides the storage area and spare area to hold the error code bits in use by the error correction method of the system.
