Giant memory thanks to tiny capacitors Page: 1 German-Korean research team produces a permanent memory using a new procedure and thereby sets a memory density record.
As a result of today's consumers demanding it, electronics of the future are becoming increasingly smaller and lighter, as well as faster and more powerful. A method now developed by scientists at the Max Planck Institute of Microstructure Physics in Germany, Pohang University of Science and Technology (POSTECH) in Korea and the Korea Research Institute of Standards and Science (KRISS) may help to achieve these goals.
The new method enables the production of particularly densely-packed memory storage. Using an extremely finely perforated mask, the researchers housed capacitors made out of platinum and lead-zirconate-titanate (PZT) with a density of 176 billion bits on a square inch - a world record for this material. Such storage is easy to control and can save memory permanently. Chips made from this material could therefore replace current working memories in which saved bits have to be constantly refreshed.
Whether MP3 players, camera mobile phones, navigation systems or notebooks, all have to be compact but also able to store increasing large amounts of music, images, films or maps, and process them quickly. Innovative new memory would contribute greatly towards making electronics smaller and more powerful, especially if it were able to save information permanently, but still process data as quickly as the DRAMs on which computers currently store programs. "Permanent memory of this kind can be produced very simply and efficiently using our methods," said Dietrich Hesse, a scientist at the Max Planck Institute of Microstructure Physics in Halle, Germany, who played a prominent role in the work of the research team.
According to the source the memory can save data permanently, much like a hard drive. but can process it as quickly as a working memory. Furthermore; scientists can control each memory precisely, even though they are only 60 nanometers apart from one another.

Mmmm solid-state, high-density memory for the win...
