章節(jié)摘錄

插圖：What is solid state storage？ Solid state storage （sometimes calledflash memory） is a technology that stores data in erasable, rewritable cir-cuitry, rather than on spinning disks or streaming tape. It is widely used inportable consumer devices, such as digital cameras, MP3 music players,PDAs, and cell phones. It is also used as an alternative for hard disk storage in some notebook computers and netbooks.Solid state storage is removable and provides fairly fast access to data. Itis an ideal solution for storing data on mobile devices and transporting datafrom one device to another.How does solid state storage work？ Solid state storage contains agridwork of circuitry. Each cell in the grid contains two transistors that act asgates. When the gates are open, current can flow and the cell has a valuethat represents a "1" bit. When the gates are closed by a process calledFowler-Nordheim tunneling, the cell has a value that represents a "0" bit.Very little power is required to open or close the gates, which makes solidstate storage ideal for battery-operated devices, such as digital camerasand PDAs. Once the data is stored, it is non-volatile——the chip retains thedata without the need for an external power source.Solid state storage provides fast access to data because it includes no mov-ing parts. This storage technology is very durable——it is virtually imperviousto vibration, magnetic fields, or extreme temperature fluctuations. On thedownside, the capacity of solid state storage does not currently match thatof hard disks. The cost per megabyte of solid state storage is slightly higherthan for magnetic or optical storage.
