New 3D memory architecture revives old camera technology to smash through AI memory wall - NAND + DRAM hybrid promises to make memory cheaper, faster and with 'unlimited endurance'
- Researchers have created a NAND-DRAM hybrid, inspired by legacy camera tech
- Indium Gallium Zinc Oxide also promises benefits over silicon
- For now, this is just a prototype that needs further work
Belgian semiconductor research hub imec has unveiled what it claims to be the first 3D implementation of charge-coupled device (CCD) memory architecture, which revives technology we’ve already seen used before in digital cameras and camcorders, but for a totally different purpose.
With 3D CCD architecture, the researchers were able to break one of the biggest bottlenecks in AI computing today – the memory wall – where GPUs and accelerators spend more time waiting for data than processing it as a result of poor memory bandwidth and power efficiency.
The new design combines the speed and rewritability of DRAM with the density and efficiency of NAND to form a type of hybrid.
Old camera tech could actually lead to future...
