NOR Flash
What is NOR Flash?
- NOR flash is a non-volatile memory that can hold the stored data even when the power is out. It also allows random data access, and provides fast reading and processing of data, which first made it ideal for code storage.
- With the increased use of mobile devices like cellular phone, PDA, digital camera, portable game consoles and MP3P, NOR flash is more widely used not only for code storage but also for data storage. It is also used in home appliances such as HDTV, DVD, Router, and GPS, and industrial and automotive uses are on the rise as well.
- SAMSUNG's NOR flash is widely recognized for its superior features. The company also provides a total solution in the form of MCP, by offering a wide range of products including SRAM, UtRAM, NAND, and DRAM.
