Researchers Create Ultrafast Memory Device

Nanyang Technological University and University of California, Berkeley, researchers have constructed a prototype ultrafast, energy-efficient ferroelectric memory device able to use light to read data. Three types of memory chips are commonly available: RAM, ROM, and DRAM, each of which has limitations. Recent research on addressing these limitations has focused on developing an energy-efficient device that is faster and more accurate than RAM. The leading candidate is ferroelectric RAM, which is made with bismuth ferrite and uses magnetic polarization to represent the ones and zeros of binary data. The newly developed FRAM chip uses halogen light to read the polarization.  Shining a light on the material does not disturb its polarization. This would eliminate errors, specifically the erasing of data, that can occur when devices use electricity to read polarization. The researchers claim their device is about 10,000 times faster than DRAM and operates on only 3 volts of electricity, compared to DRAM’s average 15 volts. The next steps toward commercializing the technology include making it smaller. The researchers published their work in the journal Nature Communications. (PhysOrg)(Nature Communications)
