Abstract: With the continued scaling of NAND flash and multi … 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 and NAND logic gates. Both use the same cell design, consisting of floating gate … 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 transistor. The original MOSFET (metal–oxide–semiconductor … 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 … 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 writing the memory is different; NOR allows random access, while NAND allows … See more Flash memory stores information in an array of memory cells made from floating-gate transistors. 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 … 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 Because of the particular characteristics of flash memory, it is best used with either a controller to perform wear leveling and error correction or … See more Multiple chips are often arrayed or die stacked to achieve higher capacities for use in consumer electronic devices such as multimedia players or GPSs. The capacity scaling … See more

WebOne way to improve flash lifetime is to use stronger error correction codes (ECC) [3][4]. Stronger ECC detects and corrects raw bit errors that happen over the lifetime of a flash … WebFlash lifetime can be extended by relaxing internal data retention time, the duration for which a flash cell correctly holds data. Such relaxation cannot be exposed externally to …
