INTRODUCTION
Nano-RAM also known as NRAM, is a proprietary computer memory technology. NRAM is a type of nonvolatile random access memory based on the mechanical position of carbon nanotubes deposited on a chip-like substrate. In theory the small size of the nanotubes allows for very high density memories.
HISTORY
Nano-RAM is a computer memory technology from the company Nantero and NANOMOTOR its invented by University of bologna and California nano systems. Nanomotor is a molecular motor which works continuously without the consumption of fuels. It is powered by sunlight. The research are federally funded by national science foundation and national academy of science.
TECHNOLOGY
Nantero's technology is based on a well-known effect in carbon nanotubes. In Nantero's technology, each NRAM "cell" consists of a number of nanotubes suspended on insulating "lands" over a metal electrode. A small dot of gold is deposited on top of the nanotubes on one of the lands, providing an electrical connection, terminal. A second electrode lies below the surface.
What is Carbon Nano Tubes ?
Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon.
They exhibit extraordinary strength and unique electrical properties, and are efficient conductors of heat.
Their name is derived from their size, since the diameter of a nanotube is on the order of a few nanometers.
There are two main types of nanotubes: single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs).
STRUCTURE OF (CNT)
STORAGE ON NRAM
The tubes can be physically swung into one or two positions representing one and zeros.
The bit itself is not stored in the nano tubes, but rather is stored as the position of the nanotubes.
The chip will stay in the same state until you make another change in the electric field.
So when you turn the computer off, it doesn't erase the memory .We can keep all the data in the NRAM and gives your computer an instant boot.
ADVANTAGES
NRAM does not require power to "refresh" it, and will retain its memory even after the power is removed.
The power needed to write to the device is much lower than a DRAM.
It uses Carbon nanotubes to give super CARBON NANOTUBES Advantages Very small in size. Low power consumption.
The read and write process are both "low energy" consuming,so NRAM can result in longer battery life in conventional devices.
Highly resistant to environmental forces (heat, cold,etc)
USES OF NRAM
NRAM could enable instant-on computers which boot and reboot instantly
PDAs with lots of memory, MP3 players with thousands of songs can replace flash memories in digital cameras and cell phones.
High speed network servers. And because the technology is considerable faster and denser, Nanterno believes NRAM could eventually replace hard disk storage.
NRAM
CONCLUSION
It's hard to imagine a more exciting area than nanoelectronics. Every day at our lab our engineers are coming up with new ideas and new ways to build products on a molecular level that have never been done before. And the whole field of nanotechnology is one that will, over the next few decades, affect just about every area of human life, from electronics to medical care and beyond, so it's great to be right there on the leading edge. Thus, with the beginning of the usage of NRAM which gives instant-on computers, we can obtain a very fast and ever existing Random Access Memory for very vast applications.
