Samsung develops mobile DRAM capable of 12.8GB/sec data transfers, making all other memory jealous

Samsung's memory labs are cranking out yet another innovation in the mobile DRAM sector, with the goal being to make the next (next) generation Galaxy Tab -- and any other mobile device relying on Samsung memory -- faster than ever. This go 'round, the crew has developed a 1Gb mobile DRAM module with a wide I/O interface for smartphones and tablets, enabling it to transmit data at 12.8GB/sec. For those keeping count, that's an eightfold increase in bandwidth compared to LPDDR2 DRAM chips, and the company has also managed to trim power consumption by 87 percent all the while. In order to boost the data transfer rate, Samsung's new wide I/O DRAM uses 512 pins for input and output, dwarfing the 32 pins used in the previous generation. Following this, Sammy's hoping to provide 20nm-class 4Gb wide I/O mobile DRAM sometime in 2013, but we're hoping to see this particular development sashay into tablets that hit the market long before then. Sadly, there's no specific word on when, but you know we'll be handing that information over just as soon as we get it.


press Release:

Samsung Develops Mobile DRAM with Wide I/O Interface

SEOUL, Korea--(BUSINESS WIRE)--Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today announced the development of 1 gigabit (Gb) mobile DRAM with a wide I/O interface, using 50 nanometer class* process technology. The new wide I/O mobile DRAM will be used in mobile applications, such as smartphones and tablet PCs.

"We will continue to aggressively expand our high-performance mobile memory product line to further propel the growth of the mobile industry."

"Following the development of 4Gb LPDDR2 DRAM (low-power DDR2 dynamic random access memory) last year, our new mobile DRAM solution with a wide I/O interface represents a significant contribution to the advancement of high-performance mobile products," said Byungse So, senior vice president, memory product planning & application engineering at Samsung Electronics. "We will continue to aggressively expand our high-performance mobile memory product line to further propel the growth of the mobile industry."

The new 1Gb wide I/O mobile DRAM can transmit data at 12.8 gigabyte (GB) per second, which increases the bandwidth of mobile DDR DRAM (1.6GB/s) eightfold, while reducing power consumption by approximately 87 percent. The bandwidth is also four times that of LPDDR2 DRAM (which is approximately 3.2GB/s).

To boost data transmission, Samsung's wide I/O DRAM uses 512 pins for data input and output compared to the previous generation of mobile DRAMs, which used a maximum of 32 pins. If you include the pins that are involved in sending commands and regulating power supply, a single Samsung wide I/O DRAM is designed to accommodate approximately 1,200 pins.

Following this wide I/O DRAM launch, Samsung is aiming to provide 20nm-class* 4Gb wide I/O mobile DRAM sometime in 2013. The company's recent achievements in mobile DRAM include introducing the first 50nm-class 1Gb LPDDR2 DRAM in 2009 and the first 40nm-class* 2Gb LPDDR2 in 2010.

Samsung will present a paper related to wide I/O DRAM technology at the 2011 International Solid-State Circuits Conference (ISSCC) being held from February 20 to 24 in San Francisco.

According to iSuppli, mobile DRAM's percentage of total annual DRAM shipments will increase from about 11.1 percent in 2010 to 16.5 percent in 2014.
