Ultra-Fast Quantum-Dot Information Storage

User rating: 4.7 / 5 after 95 vote(s)

The information-storage market is dominated by two main types: Flash memory, used in memory sticks and cell phones, and dynamic random access memory (DRAM), which is the main memory in a personal computer. Both types have their advantages and disadvantages, but a new type of memory, based on tiny atom clusters, called quantum dots, may soon displace both of them.
