What is Polymer memory
A leading technology in memory device development
Made out of electrically-conducting polymer
Relatively denser and cheaper compared to flash memory
What is a PEDOT?
The material is a blend of a negatively-charged polymer called PSS- and a positively-charged one called PEDT+
It has an ability to conduct electricity
Used widely as the anti-static coating on camera film
And also as a photo-sensitive agent
Next Generation Memory
FeRAM-works on the basis of the bistable nature of the centre atom of selected crystalline material
The FeRAM memory is non volatile: - The state of the central atom or the direction of polarization remains even if power is made off.
Fast Random Read Access.
Fast write speed.
Destructive read, limited read and write cycles.
Very low power consumption
Architecture of Polymer Memory devices
Each polymer is sandwiched between two electrodes which acts as memory
a cell
A voltage is applied between top and the bottom electrodes
Memory is represented as space charges in the polymers that are detected using electrical pulses
ADVANTAGES OF POLYMER MEMORY
Polymer memory layers can be stacked This enable to achieve very high storage capacity.
Memory is Nonvolatile
Fast read and writes speeds
Very low cost/bit, high capacity per rupee
Low power consumption
Easy manufacture, use ink-jet printers to spray liquid-polymer circuits onto a surface
10xFaster than conventional memory devices
