NAND flash erase block
Definition
The minimum unit that can be electrically erased in NAND flash memory. Erase blocks are larger than write pages (often 256 KB to 4 MB). The OS writes at page granularity but erases at block granularity, so a block containing deleted sectors cannot be cleared until all live pages in the block have been relocated.
