ReRAM – The End of Hard Drives & SSD’s as we Know Them?

Two Companies, HP & Hynix have joined forces and are currently working together developing memristor technology in the form of Resistive Random Access Memory (ReRAM).

ReRAM works in a similar way to normal RAM, but the big difference is RAM can only store data when there is power being fed to the device. ReRAM gets around this issue and is able to store data even when there is no power, similar to a USB Pen Drive (Flash Memory).

So why not use flash memory as RAM? Simple answer is transfer speed, RAM’s transfer speed is much faster than Flash Memory, and even faster than modern day SSD’s. ReRAM is able to process data at the same rate as RAM which could potentially mean loading times will be a thing of the past, boot times would be massively increased and Notebook and Netbook batteries would last longer too since ReRAM consumes less power.

In the future, because both the processing and memory functions could be conducted within the same chip, laptops and smartphones could be much thinner and much faster than they are now. Why? Because data has less distance to travel since memory and logic are performed on the same chip.

Also in Production is DDR4 Memory (RAM) although there is not a confirmed release date it is expected to represent 5% of the DRAM market in 2013 and reaching around 50% by 2015. This is due to changes required to other components as these would need updating to work with DDR4. This would be comparable to DDR3 which took approximately 5 years to achieve mass market transition over DDR2.

What we can be certain of is the speed of DDR4 will be much faster than DDR3 whilst using less power at 1.2V or less versus the 1.5V of DDR3 Modules.
