Resistive RAM is something that is gaining attention in research now-a-days. While the traditional RAMs – static, dynamic and flash – store the data (i.e. the bit) in the form of charge, R-RAM stores it in the form of resistance – apply some voltage to the “cell” and it increases its resistance and can decrease it as well when voltage is applied in another direction.
What’s the big deal? One thing that stands out is its non-volatility. Other things are less power requirement, faster access times etc. If we get non-volatility in the RAM itself while not compromising other factors – performance, more importantly, then what else we need?
