Agilent Debuts Versatest Series Model V5400 for Testing Memory Devices

6/22/2004 - Agilent Technologies Inc. (NYSE: A) introduced its Versatest Series Model V5400, which delivers the lowest cost of test across a full spectrum of memory devices. The V5400's unique dynamic algorithmic pattern generator (APG) and patented tester-per-site (TPS) architecture provide unmatched configuration flexibility and up to four times improvement over existing systems in throughput for wafer sort and final memory testing.

Compatible with Agilent's highly successful Versatest Series Model V4400, the Model V5400 overcomes the challenge of testing standard and stacked memory modules such as flash, DRAM and SRAM while offering up to 4,608 channels and 144 independent test sites, an industry-first for a single testhead. The increased performance and lower system costs helps reduce the overall cost of test for semiconductor contract manufacturers, fabless design houses and memory integrated device manufacturers.

The growing consumer demand for digital devices with added functionality and smaller footprints at lower prices has given rise to new test challenges. The devices require higher frequency test systems and the flexibility to test multiple types of memory such as flash and DRAM concurrently, while continuing to require a lower cost of test. Until now, memory manufacturers have purchased separate systems for testing the different kinds of memory embedded in handheld consumer devices. The Agilent Versatest Series V5400's complete, single, scalable platform architecture will now allow users to test standard memories, reduced pin-count devices, BIST-enabled devices and stacked memories at up to four times higher throughput compared to existing systems.

Agilent's TPS architecture makes it possible for each device under test (DUT) to receive its own set of tester resources. The dynamic APG on the Model V5400 test site module sets new standards in TPS architecture and has the ability to maximize tester resources based on the needs of the DUT. Dynamic APG can independently test up to four low-pin-count DUTs per site module. For complex tests or high pin count devices, dynamic APG can reallocate all site module resources toward testing a single DUT. Configurable solely through software, the dynamic APG enables the Model V5400 to test a broad spectrum of devices without a change in tester hardware.

Complementing the flexibility of dynamic APG is the parallelism offered by the Model V5400 testhead. As an industry innovator, Agilent has been able to increase pin count through various technologies such as the use of extensive proprietary application-specific integrated circuit (ASIC) technology in the site module. The Model V5400 with 4608 I/O pins is able to lower the cost of test by asynchronously testing up to 144 independent devices.

"The diversity of characteristics coupled with performance, form factor and density of today's varied memory devices demands a tester that offers versatility and reduces cost of test for customers," said Pi Chao, business development manager of Agilent's California Semiconductor Test division. "As a leader in memory testing, Agilent developed the Model V5400 to address these needs by focusing on a tester that contributes to increased parallelism."

Furthermore, the combination of the V5400 with the Agilent Versatest Series Model V5000, a single-site engineering development system, offers a complete solution for a broad spectrum of memory test. This compact and low-cost system permits a memory test engineer to develop programs within an office without consuming valuable production tester resources. The V5000 also shares the same site module and software interface as the V5400, ensuring seamless compatibility.
