TMCNet: Elpida Offers Industry's First DDR2 SDRAM with x32-Bit I/O Configuration

[May 15, 2008]

Elpida Offers Industry's First DDR2 SDRAM with x32-Bit I/O Configuration

TOKYO --(Business Wire)-- Elpida Memory, Inc. (Elpida), Japan's leading global supplier of Dynamic Random Access Memory (DRAM), today announced the availability of the industry's first 512-megabit DDR2 SDRAM with x32-bit I/O configuration. Elpida will begin sampling of this product by the end of this month.

In the past a DDR2 controller with x32-bit wide interface required two x16-bit I/O DRAMs. Now, Elpida offers a 512-megabit DDR2 SDRAM with x32-bit I/O configuration as a one-chip solution. The advantages of this x32-bit solution over a two 256-megabit DDR2 (with x16-bit configuration) solution are as follows:

-- Approximately 25% memory area reduction on the board

-- Fewer package balls (40 balls)

-- Approximately 20% less power consumption

-- A one-chip solution delivers low EMI and better signal quality

"Elpida's new x32-bit DDR2 product realizes a simpler board layout and it can support a four-layer board," said Yoshitaka Kinoshita, executive officer for Elpida's Digital Consumer Division. "Elpida's one chip solution based on the new product is expected to reduce customer's total system costs."

Elpida developed x32-bit I/O DDR2 products to meet the need for small-size consumer electronics that feature 1.8V low-voltage operations and low-power consumption. Because the new x32-bit product is specially designed for consumer devices it is well suited for use in digital consumer appliances.

Product Features:

-- 512Mbit DDR2 SDRAM (x32-bit I/O configuration) using 70nm process technology

-- Data transfer rate: 250Mbps to 1066Mbps (1GBytes/sec to 4.2GBytes/sec per DRAM device)

-- ODT (On-Die-Termination): 50/75/150/225ohm Enhanced 225ohm ODT reduces power consumption.

-- Driver strength: normal/weak/quarter Reduces overshoot, undershoot noises

Target Market:

Digital TVs, set-top boxes (STB), personal navigation devices (PND), printers, digital still cameras, digital video recorders, projectors and more.

Mass production of the new x32-bit DDR2 SDRAM is scheduled to begin in September 2008. Because Elpida has a proven track record of device production and support for early product launches in the digital consumer market, more than 30 companies in Japan and elsewhere in Asia, North America and Europe have welcomed the product. As a result, business discussions are in progress.

Elpida will continue to develop new products as it works toward that goal.

Product specifications for the new x32-bit SDRAM are attached.

  • Seven Best Practices for Speech Analytics: Speech analytics is valuable for identifying issues in the contact center. However, limiting its use to the contact center only considers a portion of all customer interactions and subsequently only reveals a small part of the voice of the customer. This paper discusses how organizations can optimize their Speech Analytics implementation strategy to realize the promise of this exciting technology.
  • Understanding the Voice of the Customer: Today's contact centers involve a sea of information that must be captured, processed, and distributed on a daily basis. Effective use of this information enables companies to remain competitive in an increasingly aggressive and customer centric marketplace. An overwhelming percentage of the information that circulates in a contact center's audio recordings, documents, web pages, and emails is unstructured in that it resides outside of a normal structured database and cannot be managed efficiently. These unstructured items contain valuable information, yet this information historically has been difficult to organize, categorize, and access.
