For high-density data storage applications, engineers at the Indian Institute of Technology (IIT), Jodhpur, have created a resistive memory device with extremely low power consumption.
The high-performance "Memristor" device, which has a high on/off ratio, quick operation speed, good random-access memory (RAM) performance, extended retention time, and endurance of more than 150 switching cycles, is built of cadmium selenide (CdSe) quantum dots (QDs), according to officials.
They stated that this device can carry out logical processes quickly, it can also be employed as high-density storage.
“The current commercial memory technologies available in the market are Hard Disk Drive (HDD), USB flash drive, SD card, Solid State Drive (SDD), Dynamical Random Access Memory (DRAM) and Static Random Access Memory (SRAM) to store data in electronic devices. These data storage devices cannot store vast amounts of data generated by digital globalisation and the internet of things (IOTs),” said Satyajit Sahu, Associate Professor, Department of Physics, IIT-Jodhpur.
“To store the massive data in a small device, miniaturisation of memory devices is needed. But, the silicon-based memory technologies are facing serious reliability issues upon downscaling to a few nanometres. Hence, current memory technologies cannot fulfil the requirement of high-density data storage devices. Therefore, new memory technologies are needed for high-density storage,” added Sahu.
