Legacy Electronics Releases First-To-Market 4GB DDR2 DIMM Incorporating Canopy™ Technology

Allows designs of newer high-end servers and supercomputers to double DRAM memory in same socket space

SAN CLEMENTE, CA — March 15, 2005 — At the CeBIT trade show in Hannover this week, Legacy Electronics launched its newest, 4GB, dual in-line memory module (DIMM) for high-end server, workstation, and supercomputer applications.  Built on a standard board height of 30mm (1.18 inches), this DDR2 ECC-registered module uses industry-standard, 1-Gbit DDR2 components and Legacy’s Canopy® technology to produce the maximum possible memory in a low-profile DIMM at a reasonable cost.

Jason Engle, Legacy Electronics President, explained ‘The new 4GB DIMM gives Legacy a competitive edge in delivering maximum-density modules to the server market, and allows us to engage in top tier accounts that require the highest technology solutions for their products.”

“With the increase in component density of DDR2 SDRAM devices, comes a die size penalty which makes it increasingly difficult to achieve higher density modules without increasing overall module height,” says Kelvin Marino, Legacy’s director of application engineering and new product development.

He continued, “Typically, until now, 2GB DIMMs based on 36, 512-Mbit DRAMS were the largest density, 2-rank memory modules used in the market.  Now, system designers can double the amount of DRAM memory, and still achieve the best thermal characteristics and higher reliability that our Canopy® technology provides.   While there are other 4GB modules out there, none provide these advantages.”

The Legacy 4GB DIMMs are JEDEC-standard, ECC-registered DIMMs, based on CMOS DDR2 SDRAM technology, available as a 512Mx72 bit format.  Each DIMM consists of 36 CMOS DDR2 SDRAMs in FBGA packages on a 240-pin glass epoxy substrate.

The Canopy® leadless FBGA component carrier is part of Legacy Electronic’s patented, three-dimensional assembly technology, which is an alternative to conventional chip stacking.  It provides better thermal characteristics due to air gaps between devices.
