ReRAM, a chip for Storing and Processing Data

Technology don’t only bring comfort to life but to also lessen costs of living life and driving businesses. In data management, this has been proven with another laudable and interesting projects by Crossbar inc. to replace in-memory data storage with in-chip data management through crossbar technology.

Resistive Random Access Memory, RRam or ReRam is a new initiative to improve data storage and processing, different from how memory card or SD card stores data but rather use semiconductor memory.

The mechanism can be classified into four groups, viz: Anion based ReRAM, which involves redox reaction and migration of oxygen ions. The second one is Cation based RRAM, where redox reaction and cation ions are migrated, Carbon based RRAM and Oxide-based electrode.

Some characteristics of the four major categories of Reram are:
Anion-type RRAM
1. It is Compatible with CMOS fabrication technology.
2. It is reliable
3. It has reliability issues for mass product.
4. It has High forming voltage.

Cation-type RRAM
1. It works well to build multi-bit storage.
2. It has large dynamic margin.
3. ITC Diversionary voltage
4. It is not much reliable

Carbon-based RRAM
1. The chemical composition is simple
2. Well suited for integrated circuit
3. It’s not costly
4. Clarification of material properties.

Oxide-based electrode RRAM
1. It is used in opto-electronics industry.
2. It uses ultra-low operation voltage.
3. It’s applicable in integrated circuit
4. It is very reliable

What defines Resistive Memory is that the system is built on multiple layers of semiconductor (memories from silicon oxide) It is capable of using a switching material ( usually a material with silicon properties) and forming a nanofilament whenever voltage is applied in the electrodes. However, the quality of the switching material can have influence on efficiency as stated by crossbar.


How does Crossbar RRam technology works? The memory chips work by using complementary metal–oxide–semiconductor (CMOS) to build low temperature multiple arrays to build 3D ReRAM storage chips; better than the NAND flash memory.

Crossbar resistive memory does not degrade in performance and can tolerant temperature swing in devices and more durable; making it a better option over charge-based non-volatile memory (NVM) devices.

Those who want to key into this technology can be licensed by Crossbar to build a memory device that stands alone or SoC (System-on-Chip), combine microprocessor, controllers and logic together to simplify the system and enhance performance.

Instead of keeping your data in different devices and processing it from their, Reram put everything into one, as data don’t need to be sent from the processor to the storage device or sending it back to the processor, thereby, making data processing to be faster as it reduces the time needed to to process your information completely. Whereas, in NAND flash memory, the data has to be translated into the binary language before the computer can understand.

Already, there are scientists, schools and other stakeholders that are working to make things better with resistive memory. Rainer Weser also believed that the devices are far better in everything and can be multipurpose in use, especially in computing. Resistive ram could be likened to human neurons.

With this advancement in information technology, the cloud will benefit from fast speed data processing and the benefits can not just be numbered. Some of them are the following..

  • It uses lower energy when compared to Bluetooth, NAND, Eflash and SPI flash.
  • It can retain your data without power.
  • It is more denser than 3D NAND.
  • It is more scalable and stackable.
  • It has high retention years and endurance.
  • Tolerate temperature swing.
  • Lower latency and faster write.

In the future to come, we’re also expecting much success in other memory systems such as Phase-change Random Access Memory (PCRAM), Ferroelectric Random Access Memory (FeRAM) and Magneto Resistive Random Access Memory (MRAM)

    You’ve just educated one on Reram Technology. Thanks for sharing this and in no time, technology will simplify life in such a way that humans would not be that important again.
