Memory Test System
A new multifunctional memory test system that provides high-speed memory test coverage for diverse next-generation memory chips.
The T5835 achieves massive parallelism and test speeds more than double those of previous products, meeting the testing needs of next-generation memory devices with increased speed and capacity.
Throughput improvement and test cost reductions for high-speed DRAM and NAND flash test
The new T5835 has full testing functionality, from package testing to high-speed wafer testing, for any memory ICs with operating speeds up to 5.4 Gbps, including all next-generation memories from NAND flash devices to DDR-DRAM and LPDDR-DRAM. It can handle 768 devices simultaneously for final package-level testing. It additionally features functions such as an enhanced programmable power supply (PPS) for advanced mobile memories, and a real-time DQS vs. DQ function to improve yield.
Analysis and evaluation functions optimized for next-generation memory test
The T5385’s timing training function, which is indispensable for increasingly high-speed memory tests, and its high-speed evaluation and defect analysis functions based on various device data patterns, also help the new system address high device capacities and speeds than previous products. These features reduce test times and help improve yield. In addition, the new system’s scalable structure enables future flexibility. An added CPU for calculations increases its functionality, speed, and capacity.
Common platform architecture enables optimal system configuration
The T5835 utilizes Advantest’s AS2 platform, an enhanced version of the AS platform, which has a proven track record as the global standard for memory test systems. The AS2 platform comes in several models, including STH (Small Test Head), which is compact and suitable for evaluation and analysis facilities, and LTH (Large Test Head), which is suitable for full-scale volume production. Customer can select the system configuration that best suits the needs of their site, helping to reduce initial investment and improve efficiency. Digital modules are also available to upgrade for future expansion needs.
