ReRAM- Memristor Based Memory to Replace DRAM

Hewlett-Packard (HP), in partnership with Hynix Semiconductor Inc., is on the process of developing a new kind of memory that will use memristor technology.

Theories on this potential technology has been around for over 30 years, and has been envisioned by circuit theorist Leon Chua in 1971 as a missing non-linear passive two-terminal electrical component relating electric charge and magnetic flux linkage. He further defined memristor to cover all forms of 2-terminal non-volatile memory devices based on resistance switching effects, and claimed that memristor is the oldest known circuit element with its effect predating the resistor, capacitor, and inductor. (Wikipedia)

ReRAM, a new technology based on memristor is said to be potentially better than DRAM and flash memory in terms of total capacity, endurance, efficiency, and affordability. Over the next decade this ReRAM is said to replace DRAM and flash memory in the next decade.

Back to the main topic, Hewlett-Packard and Hynix Semiconductor Inc., is jointly developing this new technology and hopefully set the release of the new product next year. ReRAM will then be the first device that will be using the memristor based technology.


The aim of this new technology is to replace DRAM and flash memory, as it is said to run at least ten times faster than DRAM and flash memory and it also consumes ten times less power than DRAM or flash memory.

Experiments have also been conducted on this new technology, and shows that memristor based memory can be erased and written over many more times than flash memory. With a lower price yet more powerful than DRAM or flash memory, it is definitely an ideal innovation.

What does this impact do to PC’s and smartphones?

It is worth to note that with this new technology, it will impact on PC’s and smartphones in a positive way. First and foremost, PC’s that will have this new technology will have the advantage in terms of memory capacity since this memristor-based technology has a higher memory capacity. This new technology is capable of retaining information even when the power is off. This new technology is also energy efficient which means that your laptop could boot up much faster and longer with just one charge because it consumes less energy.

This new technology both functions as a computer and a memory storage, thus, both functions can be integrated to one chip. In this case, laptops and other devices that use this technology will most probably be faster since all the functions are in one chipset, thus, it travels in short distances. It will also most likely that laptops will be thinner this time because supposedly, two parts will be compounded into one part but still functions productively or even better. This is same as true with smartphones.

Though this highly awaited technology has garnered good points, it is worth to note that this is a recent innovation and there are still many properties and aspects of it that is yet to be considered.

    Nothing is more important to companies and private individuals other than to have less energy usage. With this new technology, laptops would be able to retain their portability that have been otherwise re-bunked due to their short battery life. Thanks for sharing this new information!

  3. Olly Chipper says:

    It’s ten times more efficient than DRAM or flash memory in both speed and power-consumption. And not only that, if you speculate it much closer, the materials used to create such a slick product is interesting. People are getting tingly hands for the moment it will be openly available in the market.
