Smarter memory: Researchers introduce next-generation RAM with reduced energy consumption

Numerous memory types for computing devices have emerged in recent years, aiming to overcome the limitations imposed by traditional random access memory (RAM). Magnetoresistive RAM (MRAM) is one such memory type which offers several advantages over conventional RAM, including its non-volatility, high speed, increased storage capacity and enhanced endurance. Although remarkable improvements have been made to MRAM devices, reducing energy consumption during data writing remains a critical challenge. A study published in Advanced Science by researchers from Osaka University proposes a new technology for MRAM devices with lower-energy data writing. The proposed technology enables an electric-field-based writing scheme with reduced energy consumption compared to the present current-based approach, potentially providing an alternative to traditional RAM.

• Durable space-based flash drive storage.

• Quantum information storage.

Coincidence!? 🤔

Scientists have stored the entire human genome on a five-dimensional crystal that’s capable of digitally storing up to 360 terabytes of information and is built to survive for billions of years. The tech could be used to create an enduring record of human, animal, and plant genomes. Some might remember the ‘Pioneer plaques,’ a pair of gold-colored metal plaques carried aboard the Pioneer 10 and 11 spacecraft that launched in the early 1970s. The brainchild of American astronomer Carl Sagan, the plaques were etched with a visual message – including a naked man and woman and a schematic of our Solar System – in case one of the craft bumped into intelligent extraterrestrial life on its travels. Now, researchers at the University of Southampton in the UK have created a 21st-century version of the Pioneer plaques using a 5D memory crystal that stores vast amounts of information for billions of years without degrading. They’ve stored the complete human genome – about three billion Gs, As, Ts and Cs – on it.

As much as I hate the idea of having to torrent 700+ GB and store 200+ GB, the difference in 480p and 1080p for this TV show I'm watching is absolutely necessary.

480p was practically unwatchable. Maybe the torrent creator used an intense amount of bitrate compression, but it doesn't matter. I felt like I was watching a podcast with a colorful screensaver. 720p and 1080p are so much better. Not to mention the 16:9 aspect ratio looks so much better.

However, this is another case of AV1 saving the day. 200+ GB is a lot, but 700+ GB would've been a deal breaker. As a result, I am once again asking torrent makers to use modern, fucking, video codecs. That 700+ GB is with H.265 (HEIC). I can't imagine what it would be with H.264. AV1 & Opus are really coming in clutch with this show.

By 2021, around 6,000 Swedes had microchips implanted in their hands, allowing them to store data like emergency contacts, social media profiles, and e-tickets for events and rail travel.

For decades researchers have been exploring how to store data in glass because of its potential to hold information for a long time -- eons -- without applying power. A special type of glass that changes color in different wavelengths of light, called photochromic glass, holds promise for stable, reusable data storage. Now, researchers have developed a doped photochromic glass that has the potential to store rewritable data indefinitely, according to research published in ACS Energy Letters. Certain types of eyeglasses get darker when exposed to wavelengths of light emitted by the sun and then shift back to a colorless lens indoors when no longer exposed to those light waves through a process called reversible photochromism. Likewise, other types of photochromic glass can switch color in response to different wavelengths of light, making this material attractive as an inexpensive and stable platform for storing vast amounts of information in a small space. But the challenge in using photochromic glass for data storage involves not only writing information into the glass but also erasing and rewriting it ad infinitum. Now, Jiayan Liao, Ji Zhou, Zhengwen Yang and a multidisciplinary team have made progress toward this goal by creating reversible, tunable patterns on photochromic gallium silicate glass.
