New device developed allowing PCs to start more quickly
US researchers have developed a new device that represents a significant advance for computer memory, allowing PCs to start more quickly.
The device could lead to the development of a PC that starts up immediately, the team at North Carolina State University said.
Traditionally, computers use two types of memory devices, volatile and non-volatile.
Volatile memory devices, such as random access memory (RAM) or the newer DRAM, allow computers to operate quickly, but are unable to save data when the computers are turned off.
Non-volatile devices, such as the flash drives found in memory cards and USB dongles, can store information for extended periods without power.
However, the new single "unified" device combines the speed of DRAM and the ability to switch to a more persistent mode of storage, according to findings published in the journal IEEE Computer.
The researchers said the device would allow computers to start immediately.
