Schlumberger Introduces Technology-Leading RDRAM Device Algorithmic Pattern Generator

Schlumberger Automated Test Equipment (ATE; San Jose, CA) has developed an Algorithmic Pattern Generator (APG) designed to improve the time-to-volume of RDRAM devices. Called rPacket Generator (rPG), it is the only pattern generation solution specifically created for Rambus that allows test engineers to write patterns in the native language of the Direct RDRAM packet protocol.

The Schlumberger rPG, which provides pattern generation for the company's new RDX2200 system, translates the normal APG memory core patterns for Rambus devices using standard APG programming concepts similar to writing traditional memory patterns. Easy to use, rPG has a minimal learning curve and makes it easy to handle interpretive changes.

The Schlumberger rPG allows full at-speed testing of the RDRAM memory core and I/O interface at up to one gigabit per second. Combined with deep vector memory of 128 Mbit per pin for testing a high speed I/O, the RDX2200 system is the most powerful single-pass test production system on the market today.

The rPG also provides full featured support for RDRAM device and RIMM module test and characterization. Using the RDX2200 system's fail capture memory, the rPG provides full-featured bitmap and failure analysis capabilities including recording which device on a RIMM has generated each failure. This feature set is key for critical design debug, design validation and yield enhancement for high volume production.
