Today the world is of digital. All the electronic devices are formalized to manipulate the digital data. The back -bone of today’s research and development “The Computer” is also a digital device. Digital by name deals with digits and all the gadgets available today (like PDA’s, laptops, etc…) need to manipulate the digital data. To manipulate first we have to store it at a place. Thus MEMORY in today’s world plays a key role and a constant research to improve the memory in today’s electronic gadgets is ON.
RAM (random access memory) is the main storage device in all digital systems. The speed of the system mainly depends on how speed and vast the RAM is. Today with increasing power need of man even the POWER consumed is also a major part to look at. By generations RAM also had under gone many changes. Some of the versions of RAM’s which are in use are DRAM, SRAM and FLASH MEMORY. DRAM (dynamic RAM) although has a capability to hold large amounts of data it is slower and volatile.
SRAM (static RAM) even superior to DRAM in speed but less denser. Even this is volatile in nature. Overcoming the volatile nature of these two FLASH MEMORY is the latest of today random access memories. Even this fails in power saving. Overcoming all these failures of above mentioned RAM’s , researchers developed a new RAM which unlike the semiconductor technology alone used by the former, uses a combination of NANOTECHNOLOGY and contemporary SEMICONDUCTOR TECHNOLOGY and is given the name NRAM.
