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

Elpida Memory, 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.Source: Elpida

... Approximately 25% memory area reduction on the board
Doesn't this mean that heat spreaders will perform better due to a smaller size to cool?

EDIT

If so, it will be easier to OC due to the RAM not heating up as much. Add that to this:
# Approximately 20% less power consumption
And you got a win / win situation here!

Hopefully cheaper than current prices too...well we can hope, and i would imagine the heat spreaders would perform better or use less material to lower prices.

Gam[/quote]If my reasoning is correct, and your's is too, it would add another "win" to an already win / win situation :rockout:

Doesnt that make it more effecent than ddr3?

I don't know if anyone just noticed, but this will enable desktops to achieve over 15-30 GBytes / sec mem bandwith.

Right now your typical dram consists of 8x16M = 64 bit path for the memory module.

These new chips will be able to get 128 per module. So we could be looking at a future path to 256 and 384 bit DDR 2/3 Possible DDR4. For desktops.

Awesome stuff

I don't think these are for desktops...

I might be missing something here, but this doesn't sound compatible with normal desktop JEDEC DDR2 standard ("PC3200", etc.) using current on-DIMM ASICs which present the individual chips to the system as the bank configurations they expect, unless they are also launching some other ASICs along with these chips to make it look the same as 'normal' JEDEC DDR2 DIMMs.

Well well, looks like Elpida is trying to gain a better foothold with the enthusiast crowd. PErhaps getting legendary like micron d9s?

To repeat, this is NOT desktop memory so they can't be aiming for the "enthusiast" desktop crowd and competing with the Micron D9 which is 8bit memory.
