Web28 mei 2024 · Flash memory is non-volatile memory and can be erased and reprogrammed on the memory cell block. The write operation of any flash device can only be done in an empty or erased cell, so in most cases, the erasure must be performed before the writing. In general, the NAND devices perform the erasure operation easily. WebThe benefit of having sectors is that the Flash memory is sector-erasable, meaning you can erase one sector at a time. In the past, erase commands erased the entire memory chip - therefore to keep a working copy of that data during run-time, an application required additional memory.
