ABSTRACT

Introduction Dynamic random access memory (DRAM) provides high-speed storage and retrieval of data, and is a key component in computers. NAND flash memory is essential in devices, such as smart phones, that require large data storage or fast recording. The demand for memory grows in tandem with sales of computers, smart phones, and other electronic devices. In 2010, global DRAM sales totaled $39.2 billion and NAND flash memory sales totaled $17.3 billion.2
