Generally, the boot code will copy NAND flash content to SDRAM. Using hardware ECC, the NAND flash data validity will be checked. Upon the completion of the copy, the main program will be executed on the SDRAM.

If so, the ECC must have a length of at least 7 bit. The ECC of each word is probably written to the same nonvolatile mem as the word itself. Therefore the same limitations apply. I.e. between erases, only additional bits can be set.

Why is the ECC still enabled after writing the same page twice without erasing in S29GL-T device (erase → write → write to the same page)? ECC bits are also stored in flash non-volatile memory cells, so ECC bits can only be changed from ‘1’ to ‘0’. In the first write operation, ECC parity is calculated and written to the hidden ...

Unfortunately, the characteristics of the two memory types don’t allow simple switching from one to the other. in willing sacrifice by gemeropeWeb29 de jul. de 2024 · QSPI NOR flash is usually writable down to the individual bytes (except for some ECC protected devices as we’ll see later on). However, like all flash memories, NOR must be erased in large “chunks”. Those chunks can often be subdivided and erased in smaller subunits albeit with a performance penalty. onof stockhttp://events17.linuxfoundation.org/sites/events/files/slides/An%20Introduction%20to%20SPI-NOR%20Subsystem%20-%20v3_0.pdf on of so4Web9 de abr. de 2024 · 1、Nand Flash组织架构.
