Researchers from North Carolina State University have developed a new device that represents a significant advance for computer memory. Until now, there are two major categories of memories, the fast "volatile" memories that can maintain data only as long as they have power (such as the RAM and DIMMs), and the slow "nonvolatile" memories that can maintain data for long periods of time without power, such as the flash memory.
The new device is called double floating-gate field effect transistor (FET). They will replace the single floating-gate FETs in slow nonvolatile memories. The new memories that will appear, will have the same speed as today's volatile memories, but they also will be able to maintain data without power! Imagine this: You power off your PC and all data in RAM are saved. Then you turn it on... The PC will be turned on faster than the monitor. Read the original article here.
