Today NAND Flash memory is used for data and code storage in digital cameras, USB devices, cell phones, camcorders, and solid-state disk drives. Figure 13.6.1 shows the memory-density trend since 2003. To satisfy the market demand for lower cost per bit and higher density nonvolatile memory, in addition to technology scaling, 2b/cell MLC technology was introduced. Recently, MLC NAND flash memories with more than 2b/cell [1,2] have been reported.
