As they say, every passing day is history and so would we be, as we are a constantly evolving race, and every small invention is a celebration, for it all adds up to our success. Somewhere, somehow the data of the present times has to be stored. The hard drives are not good for more than 40 years, for they get affected by the magnetic field.
The optical discs can stay put for a century and not more for the oxygen or the moisture renders them lame. Considering all this, the only good option is the semi-conductors which can do the storage thing for 1000 years when maintained at humidity less than 2%. Japanese Keio University, Sharp Corp and Kyoto University at the 2009 Symposium on VLSI Circuits have showcased the Digital Rosetta Stone (DRS), which is a stacked layer of wafers mounted with ROM and engulfed with SiO2. The entire setup is supported by a wireless power supply and signal communication.
The researchers have used the electronic-beam direct writing technology to save data on the mask ROM. The SiO2 packaging serves as a slate. On connection with a wafer reader, this slate does the wireless power and signal communication bit. If four of such wafers (measuring 15 inches) are made using 45nm CMOS technology and stacked, the overall memory capacity would sit at a whopping 2.5 Tbits. Distributing 56Mw energy to the slate using four-way transmission (slate and reader 0.2mm apart) would help achieve a transmission speed of 150Mbps. Guess the world finally has the secret to storage till eternity and as always it is time to rejoice.
