Soon, 1,000 times faster phase change memory-based storage device

Washington , Fri, 03 Jun 2011 ANI

Washington, June 3 (ANI): Researchers will soon demonstrate a phase-change memory storage device called 'Moneta' that is believed to be thousands of times faster than a conventional hard drive.


Additionally, it will be up to seven times faster than the current state-of-the-art solid-state drives (SSDs).


The storage system uses phase-change memory (PCM), an emerging data storage technology that stores data in the crystal structure of a metal alloy called a chalcogenide.


The researchers have informed that PCM is faster and simpler to use than flash memory - the technology that currently dominates the SSD market.


"As a society, we can gather all this data very, very quickly - much faster than we can analyze it with conventional, disk-based storage systems," said Steven Swanson, professor of Computer Science and Engineering and director of the Non-Volatile Systems Lab (NVSL).


"Phase-change memory-based solid state storage devices will allow us to sift through all of this data, make sense of it, and extract useful information much faster. It has the potential to be revolutionary," he added.


According to researchers, Moneta uses Micron Technology's first-generation PCM chips and can read large sections of data at a maximum rate of 1.1 gigabytes per second. It can write data at up to 371 megabytes per second.


For smaller accesses (e.g., 512 B), Moneta can read at 327 megabytes per second and write at 91 megabytes per second, or between two and seven times faster than a state-of-the-art, flash-based SSD.


The storage device also provides lower latency for each operation and is expected to reduce energy requirements for data-intensive applications. (ANI)
