Gold-Plastic Memory
Abstract:
Taiwanese researchers have been able to make a reliable and inexpensive nonvolatile memory array, which is made out of a mix of plastic and gold nanoparticles. The array is a 16-byte device called an organic nonvolatile bistable memory.
Attempts to make organic nonvolatile memory have been going on for a while now and are continuing. The quest is to make devices from plastic and other carbon-based chemicals as they can be manufactured cheaply using printing processes. But these organic memory devices usually tend to break down in air and under the stress of many read-write cycles whereas gold-plastic based memory can endure more than 1,000 switches and retains its data for approximately 10 days even when exposed to air. Yet, different researchers are pursuing organic nonvolatile memory devices using either nanoparticals such as carbon-60 embedded in the plastic or by using the plastic as part of an organic transistor structure.
