In single-level cell (SLC) devices, each cell stores only one bit of information. Multi-level cell (MLC) devices, including triple-level cell (TLC) devices, can store more than one bit per cell. The floating gate … See more Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR See more Block erasure One limitation of flash memory is that it can be erased only a block at a time. This generally sets all bits in the block to 1. Starting with a … See more NOR and NAND flash differ in two important ways: • The connections of the individual memory cells are different. • The interface provided for reading and … See more Multiple chips are often arrayed or die stacked to achieve higher capacities for use in consumer electronic devices such as multimedia … See more Background The origins of flash memory can be traced back to the development of the floating-gate MOSFET (FGMOS), also known as the floating-gate … See more 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 … See more Because of the particular characteristics of flash memory, it is best used with either a controller to perform wear leveling and error correction or specifically designed flash file systems, which spread writes over the media and deal with the long erase times of NOR … See more

Web\$\begingroup\$ One question would be if blocks routinely "go bad" in the sense of suddenly reading back longstanding data erroneously, or if they "go bad" in the sense of being unable to write new data and read it back reliably after an erase has been performed to re-use that block. \$\endgroup\$ – Chris Stratton
