Saving information under the storage gadgets like Floppy drives, Magnetic Tape drives, hard drives, SRAM, FLASH, Compact-Disc, DRAM, and so on is essential for the data technology globe. The company developing on the requirements to save information is highly developing. We need large information capacity and large information transfer limits. The present fashion storage gadgets cannot obtain this need.
Nanotechnology is beneficial to model large information compression storage gadgets including larger information limits. Ultrahigh storage has densities up to 1 Tb/in2 or is obtained through methods of local-probes to read back, write, and remove information under most thin polymer films. The method of scaning-probe-based thermomechanical data-storage is named as “millipede” from inside which includes ultrahigh density and great information rates. Great information rates are obtained through parallel function of great 2D arrays including thousands of cantilevers/tips micro/nanomechanical which is able to batch-fabricated through methods of silicon surface-micromachining. The basic parallelism, the densities of ultrahigh areal and the little procedure determination might include outlooks and chances to use in fields beyond envisaged.
The materials are constructed in which physical constraints like volume rang, length, area from 1nm to 100nm. The characters of materials like chemical, physical etc based on this scale are distinct from usual scale. Ultimately, it results in a robotic gadget at nanoscale dimensions which can arrange atoms automatically to make molecules of the particular chemical compounds depending on modern method “universal assembler”. For example, diamond is made from the robot, from basic carbon atoms including low rate and great greatly hard, size, and less weight.
It is concluded on the semiconductor memory chips that depend on magnetic hard drives and silicon to govern the information-storage retail and they include their drawbacks like magnetic information storage that has not increased real density 250 Gbit/in2. In the same way, FLASH Memory chips, DRAM, and SRAM includes the drawbacks of many Transistors per chip and hurdles to lessen feature size (2λ).
