A new memory technology promises to store more data at less cost than the expensive-to-build silicon chips used by popular consumer gadgets including digital cameras, cell phones and portable music players. The magical ingredient isn?t smaller transistors or an exotic material cooked up by the semiconductor industry.It?s a plastic. Researchers at Princeton University and Hewlett-Packard Co.?s HP Labs developed the memory, technically a hybrid that contains a plastic film, a flexible foil substrate and some silicon. The findings appear in the journal Nature on Thursday. More at MSNBC.
