Computer Memory
Computer Memory giant Samsung has unveiled an 8-gigabit flash memory chip based on the 60-nanometer process, as well as a 2-gigabit DDR DRAM computer memory chip based on the 80-nanometer process.  Samsung leads both the flash and DRAM markets as Intel dominates the processor market. Flash chips, which retain data after a host computer is turned off, are used in flash cards and cell phones, while DDR DRAM is used inside PCs. Both chips hold far more data than current chips and are smaller, which should make them cheaper and more powerful. The flash chip allows designers to put up to 16 gigabytes of data on a single memory card. 16GBs of memory translates into storage of up to 16 hours of DVD-quality video or 4,000 MP3 audio files. The density in the flash chip was partially achieved through the use of a 3D cell transistor structure. Other companies, such as Matrix Semiconductor in the United States, have also adopted 3D circuitry.
