SMART Modular Technologies Adds Dynamic Burn-In to Its Enterprise Class Memory Testing Process

Addressing the Industry's Need for High-Reliability Server Modules, SMART Teams With Aehr Test to Develop Its Latest Test Process

FREMONT, CA--(Marketwire - March 25, 2008) - SMART Modular Technologies (WWH), Inc. (SMART) (NASDAQ: SMOD), a leading independent manufacturer of memory modules, embedded computing subsystems, and TFT-LCD display products, today announced it has added Test During Burn-in (TDBI) to its Enterprise Class Memory (ECM) testing process. SMART's new TDBI procedure applies functional patterns, temperature, and voltage for screening or eliminating marginal DRAM devices which can cause time and stress dependent failures. Without this level of burn-in, these flaws could result in early lifetime failures for the memory device.

The industry demands high-quality DRAM memory modules. This is clearly demonstrated by OEMs' stated objectives to reduce defective parts per million (DPPM) rates to below 1000 DPPM/module in their high-end applications such as servers and routers. Dynamic burn-in combined with its proprietary ECM testing process gives SMART the ability to deliver memory modules that conform to specified failure in time (FIT) rates.

To implement its new test procedure, SMART worked with Aehr Test Systems (NASDAQ: AEHR), a worldwide supplier of semiconductor test and burn-in equipment, to design and develop the burn-in boards and test software. SMART's new TDBI process uses Aehr Test's MTX-Fp+ system, which is a massively parallel TDBI system featuring 128 data I/O channels, enhanced pattern generation, and failure detection capability. As part of SMART's comprehensive approach to test, each cell in every DRAM is exercised during the 12-hour burn-in cycle at 125°C. Additional tests are performed after burn-in as part of SMART's comprehensive ECM testing process.

"The MTX-Fp+ system adds a versatile tool to our ECM testing process, supporting our continual drive to eliminate device failures for our customers who require extremely high reliability levels," stated Larry Alchesky, SMART's Senior Manager of Test Engineering.

Since each application stresses memory differently, SMART works closely with its customers to correlate any latent defect or single bit error (SBE) issues by customizing its testing procedures to simulate and exceed actual system conditions. By combining dynamic burn-in and ECM testing, it is SMART's ongoing goal to consistently deliver highly reliable memory modules.

"We are very pleased that SMART has chosen our MTX-Fp+ for reliability testing of their advanced DIMMs," said Bill Barraclough, Director of Product Marketing at Aehr Test. "The MTX-Fp+ system lends itself well to SMART's need for a high-quality, cost-effective method for collecting reliability data, and we expect that SMART's leadership in this area will lead other companies to validate their products' reliability using our MTX systems."
