Viking InterWorks ships 576Mb Rambus NexRIMM

Extensive experience in stack technology brings forth new 576Mb SORIMM Form-Factor Module from Viking InterWorks

Viking InterWorks, a Sanmina-SCI Company (Nasdaq: SANM - News) and designer and manufacturer of memory modules, today announced it is currently shipping 576Mb Rambus DRAM-based NexRIMM modules based on 288Mb RDRAM components. The NexRIMM is similar to a JEDEC-standard SORIMM module with slightly increased thickness. Additionally, this module family is fully RoHS (Restriction of Hazardous Substances) compliant, meeting the European Union's (EU's) Directive (2002/95/EC) that requires the removal of a number of hazardous substances, including lead and other materials, from electronic components, products and assemblies by July 1, 2006.
 
"Development for this 576Mb NexRIMM module was requested by key telecommunications OEMs requiring higher-density modules than the existing 288Mb maximum, while still maintaining a small form factor," explained Mark Ellsberry, Vice President of Marketing for Viking InterWorks. "Our VR6S561826xx, 128Mx18-bit, 160-pin RDRAM NexRIMM is built with sixteen CMOS 288Mb (16Mx18-bit) WBGA RDRAM devices that are mounted using a unique two-PCB stack. The design also incorporates an EEPROM for Serial Presence Detect, and decoupling capacitors are mounted on the circuit boards for each RDRAM. NexRIMM modules are intended for mounting into Rambus-standard 160-pin SORIMM(TM) sockets."

Viking InterWorks' NexRIMM product family addresses the needs of customers designing space-constrained systems. The Single-Channel NexRIMM is a cost effective, small volumetric form-factor solution that allows up to 16 devices per module to be installed in a Rambus-standard SORIMM(TM) socket. Conventional SORIMM modules only allow up to 8 devices. By maintaining electrical compatibility and Rambus channel specifications, legacy systems can be upgraded with minimal or no redesign of the host system.

"With the multitude of telecommunications OEMs still requiring Rambus DRAM as their memory solution, it is essential that we deliver unique and innovative solutions. We have seen an increased need for Rambus DRAM modules in higher densities, while still maintaining small form factors," stated Adrian Proctor, Director of Product Marketing for Viking InterWorks. "Therefore, we utilized our experience with stacking technology to enable this need for increased memory capacity.

"The use of Rambus Signaling Level (RSL) technology permits up to 1066 MHz transfer rates while using conventional system and board-design technologies. RDRAM devices are capable of sustained data transfers at 938ps per two bytes (7.5ns per 16 bytes).

Sanmina-SCI continues to advance its technology leadership role by proactively developing products required within the telecommunications market, in addition to implementing RoHS-compliant processes and products in advance of the July 1, 2006 deadline.
