Micron has introduced a series of NAND flash memory ICs that offer higher density with solid performance and endurance for mass storage applications. These features are available in a diverse portfolio of multi-level cell (MLC) and single-level cell (SLC) NAND devices with distinct features, functionality and performance. MLC NAND is popular for higher-density storage such as SSDs, tablets, smart phones, and other wireless devices. SLC NAND is designed for high-performance, high-endurance and low-power small form-factor applications. Security features include write protect, block lock, permanent block lock, and lock tight.
