NAND, on the other hand, has a much coarser write granularity. On NAND flash, data can only be written in pages, typically 4 KiB at a time for NAND SLC (8 KiB or more for NAND MLC).

The low-level interface to flash memory chips differs from those of other memory types such as DRAM, ROM, and EEPROM, which support bit-alterability (both zero to one and one to zero) and random access via externally accessible address buses. NOR memory has an external address bus for reading and programming. For … WebDuring the lifetime of a storage medium, additional bad blocks may occur (so-called “Grown Bad Blocks” or “Runtime Bad Blocks”). This is completely normal, and flash manufacturers cannot avoid this in advance. The most common cause is a failure of the isolation layer of a NAND transistor when the high voltage needed to erase a cell is ...
