Protonic Memory
One of the biggest horrors of the computer age is to be working on a document not yet saved to the hard drive and lose everything because of a power outage or a system crash that forces the operator to shut down the computer. Attempts to create circuits that store the information when the power is interrupted have used high voltages, which quickly wear down computer electronic components, and have been expensive. Some scientists have applied for a patent on a prototype memory retention device that is inexpensive, low-powered, and simple to fabricate that may be the future of protecting vital data when suddenly lost without being save. To transmit data, the device uses embedded protons, which remain where they are when the power turns off, thus preserving the information. In devices such as DRAM's (dynamic random access memory), typically based on electron flow, the information is lost when the power is turned off.
