Tokyo, Japan. Advantest has launched its new T5833 system, a cost-efficient, high-volume test system capable of performing wafer sort and final test of DRAM and NAND devices.
The company said that amid surging sales of mobile electronics, DRAMS, NAND flash memories, and multichip packages are evolving toward higher speeds and greater device capacities. Internet and cloud servers also are driving demand for faster, higher-capacity ICs. Yet the cost of testing today’s array of memory devices is an obstacle for chipmakers, which urgently require solutions that can deliver high functionality, high performance, and low cost of test (COT). Advantest’s new, multifunctional T5833 memory test system meets these needs, the company said, delivering both wafer-sort and final-test capabilities for a full range of memory devices, including LPDDR3-DRAMs, high-speed NAND flash memories, and next-generation non-volatile memory ICs.
With a parallel test capacity of 2,048 devices for wafer test and 512 devices for final package test, the T5833 lowers costs by significantly reducing test time and boosting throughput. In addition to supporting known good die (KGD) testing at a maximum speed of 2.4 Gb/s, the T5833 also features a flexible site CPU architecture with multiple CPUs that enables optimized control of test processes.
The new system offers high-speed failure address storage and failure analysis capability, also known as memory redundancy. The speed of these two functions, both of which are indispensable for wafer sorting, reduces test time while enabling the recovery of more ICs for improved yield. In addition, both operations are scalable by making adjustments such as adding more CPUs for calculations.
Utilizing Advantest’s AS modular memory test platform, the T5833 allows customers to choose the optimal system configuration for their needs, from engineering stations to large volume-production systems. This extendibility allows the T5833 to handle future generations of devices and achieve higher throughput, which provides greater return on investment.
“Combining industry-best performance and low cost of test, the T5833 maximizes the efficiency of customers’ investments,” said Masuhiro Yamada, executive vice president, Memory Test Business Group, Advantest.
The T5833 tester joins the T5503HS system in Advantest’s family of memory test systems, which has a worldwide installed base of more than 8,000 units.
Shipments of the T5833 to customers began last month, and the company discussed the system at SEMICON West this week.
