 It is a time now that you can switch off your PC with a flash and when you switch it on again in just a second you see all your programs which you left open are there and all applications running smoothly.
US researchers at Hewlett-Packard have proven them right with the discovery of an electrical circuit that could lead to a computer you never have to boot up.
The newly discovered circuit element – called a memristor – could enable PCs that start up instantly, and laptops that retain your session information long after the battery dies.
The HP team – led by Stanley Williams – has developed a mathematical model and a physical example of a memristor, which they described in the journal Nature.
The discovery is more than an academic pursuit for Williams, who said the finding could lead a new kind of computer memory that would never need booting up. Conventional computers use Dynamic Random Access Memory or DRAM, which is lost when the power is turned off, and must be accessed from the hard drive when the computer goes back on. But a computer that incorporates this new kind of memory circuit would never lose it place, even when the power is turned off.
