New 'FeTRAM' is promising computer memory technology

27 Sep 2011 West Lafayette - Researchers are developing a new type of computer memory that could be faster than the existing commercial memory and use far less power than flash memory devices. The technology combines silicon nanowires with a "ferro-electric" polymer, a material that switches polarity when electric fields are applied, making possible a new type of ferro-electric transistor.

"It's in a very nascent stage", stated doctoral student Saptarshi Das, who is working with Joerg Appenzeller, a professor of electrical and computer engineering and scientific director of nano-electronics at Purdue's Birck Nanotechnology Center.

The ferro-electric transistor's changing polarity is read as 0 or 1, an operation needed for digital circuits to store information in binary code consisting of sequences of ones and zeroes. The new technology is called FeTRAM, for ferro-electric transistor random access memory.

"We've developed the theory and done the experiment and also showed how it works in a circuit", he stated. Findings are detailed in a research paper that appeared inNano Letters, published by the American Chemical Society.

The FeTRAM technology has non-volatile storage, meaning it stays in memory after the computer is turned off. The devices have the potential to use 99 percent less energy than flash memory, a non-volatile computer storage chip and the predominant form of memory in the commercial market.

"However, our present device consumes more power because it is still not properly scaled", Saptarshi Das stated. "For future generations of FeTRAM technologies one of the main objectives will be to reduce the power dissipation. They might also be much faster than another form of computer memory called SRAM."

The FeTRAM technology fulfills the three basic functions of computer memory: to write information, read the information and hold it for a long period of time.

"You want to hold memory as long as possible, 10 to 20 years, and you should be able to read and write as many times as possible", Saptarshi Das stated. "It should also be low power to keep your laptop from getting too hot. And it needs to scale, meaning you can pack many devices into a very small area. The use of silicon nanowires along with this ferroelectric polymer has been motivated by these requirements."

The new technology also is compatible with industry manufacturing processes for complementary metal oxide semiconductors, or CMOS, used to produce computer chips. It has the potential to replace conventional memory systems. A patent application has been filed for the concept.

The FeTRAMs are similar to state-of-the-art ferro-electric random access memories, FeRAMs, which are in commercial use but represent a relatively small part of the overall semiconductor market. Both use

ferro-electric material to store information in a nonvolatile fashion, but unlike FeRAMS, the new technology allows for nondestructive readout, meaning information can be read without losing it.

This non-destructive readout is possible by storing information using a ferro-electric transistor instead of a capacitor, which is used in conventional FeRAMs.

This work was supported by the Nanotechnology Research Initiative (NRI) through Purdue's Network for Computational Nanotechnology (NCN), which is supported by National Science Foundation.
