A next-generation B6700D memory burn-in tester to meet growing global customer demand for server and mobile data-storage solutions during the memory market’s current super cycle has been unveiled by Advantest. By measuring the functions of NAND flash and DRAM memory devices during burn-in, this new tester delivers both high throughput and a low cost of test.

With the semiconductor memory market expected to grow significantly in the future, chip makers require a fast, high-volume test solution to keep pace with their customers’ growing demand.

The dual-chamber B6700D fulfills this need by testing as many as 48 burn-in boards in parallel at speeds up to 10 MHz, which helps memory producers get their newest products to market faster while also reducing testing costs.

The tester uses a high-capacity power supply that delivers a maximum of 256A per burn-in board – twice that of the first-generation B6700 tester.

In addition, it has twice the driver pin resources as its predecessor, enabling it to reach higher testing frequencies.

In another advance over its predecessor, the B6700D can maintain or increase parallelism to keep throughput high as the number of stacked NAND die per package increases in the future.

Additionally, the tester’s oven can replicate operating conditions while controlling temperature to within one tenth of a degree.

The new B6700D runs on the same operating system as the earlier B6700, making the testers fully compatible. The bad block memory (BBM), universal buffer memory (UBM) and data pattern memory (DPM) functions are supported to enable NAND device testing.
