Samsung is promising to bring us handsets with Flexible AMOLED screens Next year, but you do not have to be a world-renowned scientist to understand that without a flexible set of components, we will not be able to reach the day when we will see fully flexible computers and devices.

Another important step in realizing this vision is coming from the Korea Institute of Science and Technology (KAIST), a group of scientists Developed Resistive Random Access Memory (RRAM), volatile, fully active and most importantly - fully flexible.

This is not the first time the best minds have tried to create But up to now the developments have been limited by the limitations of the materials used, which created interruptions between the memory cells and did not allow for the performance required from random access memory.

The new memory in the Tachlit display. Soon in the store nearest you?

KAIST researchers used a set of Memristors (A component that "remembers" the amount of charge flowing through it, allowing Information in this way) - Two aluminum bars are connected by a titanium dioxide Memristor which is enriched in oxygen at the top. Applying a third voltage to the upper aluminum electrode will "push" the oxygen ions into the titanium and reduce its resistance, a condition which is defined as "logical 1". Applying positive voltage on the same electrode will result in the attraction of the oxygen ions and a high resistance state, which will be considered a logical '0'.
Flexible transistors have been added to the array in question, preventing a current designed to read the Memristor state when it has high resistance "will travel" to another component - thus creating the long-coveted flexible memory component, which manages to eliminate the interference between the various memory cells.

The Memristor components are considered a promising potential replacement for modern DRAM memories. Will they also bring us the "Flexible Computer Revolution"?

The researchers call the achievement a "crucial step" on the path to realization of Flexible and flexible systems, although they also obviously expect a lot more work - will have to demonstrate the ability of memory to work properly on large-scale systems as well as find a way to reduce its physical size and improve its density (the flexible model created by KAIST stores 64 bit a square inch face area, when Modern constant mode offer a density greater than that according to 100 million, plus or minus).

It will be a fair number of years to the day when we can fold our laptop into a few pieces and tuck it in the pocket - but it seems that we are definitely on the right track.
