Advantest Launches New T5383 Memory Test System


New Memory Test System Boosts Throughput, Slashes Test Cost

TOKYO, Japan, October 31, 2006 - Advantest Corporation (TSE: 6857, NYSE: ATE), today announced the availability of its new memory test system, the T5383, for multipurpose memory devices such as DRAM, SDRAM, and DDR SDRAM, as well as flash memory and package test of MCP and other devices.

Following the release of Windows VistaTM*1, multipurpose memory chips such as DRAM are predicted to enjoy continued strong growth, with sales of personal computers adding to the increased demand generated by the consumer electronics sector. Yet as competition has intensified in the marketplace for cellular phones, digital cameras, and other products, spurring product diversification and forcing prices down, makers of DRAM and flash memory devices have been required to keep pace: while device speed and memory capacity grow, prices drop. This diversification of applications has also boosted demand for MCP (multi-chip package) type memory devices. In this market environment, automatic test equipment must contribute by offering lower test costs. Additionally, MCP manufacturers have begun to seek KGD (known good die) testing at wafer level.

Advantest’s new T5383 shares the compact floor space requirements of the company’s previous model, the T5377S, but offers a 50% higher parallel test capacity of 384 devices and performs twice as fast, with a maximum test speed of 286MHz / 572Mbps in DDR mode. The new system also offers high speeds and high throughput on at-speed test and KGD test for DRAM wafers, as well as flash memory package test.
Other developments of note include a 200% improvement over the previous model in the speed of the redundancy analysis and repair hardware (the MRA4ev3 option), which is widely used in DRAM front-end test. Calibration time has also been reduced by 90% - further contributing to reduced test cost.

In response to the problem of temperature changes causing probe cards to warp, which has recently become an issue on semiconductor manufacturing lines, Advantest has developed a new mechanism to prevent card warpage, and equipped the T5383 with a proprietary wafer motherboard. These advances completely eliminate the previously inevitable 1-2 hour wait subsequent to probe card insertion. Now, testing can commence immediately.
