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 are named after the NAND and NOR logic gates. The individual flash memory cells, consisting of floating-gate MOSFETs , exhibit internal characteristics similar to those of the corresponding gates.A flash memory device typically consists of one or more flash memory chips (each holding many flash memory cells) along with a separate flash memory controller chip.
NAND flash memory is a type of nonvolatile storage technology that does not require power to retain data. An important goal of NAND flash development has been to reduce the cost per bit and to increase maximum chip capacity so that flash memory can compete with magnetic storage devices, such as hard disks. NAND flash has found a market in devices to which large files are frequently uploaded and replaced. MP3 players, digital cameras and USB flash drives use NAND technology.▶ View More
NOR flash memory is one of two types of nonvolatile storage technologies. Nonvolatile memory does not require power to retain data.NOR and NAND use different logic gates -- the fundamental building block of digital circuits -- in each memory cell to map data.▶ View More
eMMC is the abbreviation of Embedded MultiMedia Card, is easy to use as embedded multimedia card (MMC) memory . eMMC encapsulates a integration of a controller, provides a standard interface and memory management, make the mobile makers will be able to focus on theire energy to develp the other parts and shorten the time for the product to be launched into the market.▶ View More
Dynamic random-access memory (DRAM) is a type of random access semiconductor memory that stores each bit of data in a memory cell consisting of a tiny capacitor and a transistor, both typically based on metal-oxide-semiconductor (MOS) technology.DRAM typically takes the form of an integrated circuit chip, which can consist of dozens to billions of DRAM memory cells. DRAM chips are widely used in digital electronics where low-cost and high-capacity computer memory is required. One of the largest applications for DRAM is the main memory in modern computers and graphics cards.
