Wear-Leveling
Flash memory can be erased a limited number of times. This number is called the erase cycle limit
or write endurance limit and is defined by the flash array vendor. The erase cycle limit applies to
each individual erase block in the flash device.
iDiskOnChip uses a wear-leveling algorithm to ensure that consecutive writes of a specific sector
are not written physically to the same page in the flash. This spreads flash media usage evenly
across all pages, thereby maximizing flash lifetime.
