Memory and integrated systems test reach record revenue at Teradyne

Record revenue in memory and integrated systems test helped Teradyne lift third-quarter sales to $1.306 billion, up 70% from a year earlier, as AI spending generated demand across more of its test portfolio.

Semiconductor Test contributed $1.072 billion, with Product Test adding $138 million and Robotics $96 million. Total sales exceeded the top of the company's guidance, although they were slightly below the $1.329 billion recorded in the second quarter.

“Demand extended across the AI value chain, from memory and hard disk drive test to high-speed interconnect and robotics,” said chief executive Greg Smith.

Since the quarter ended on 27 September, Teradyne has announced equipment addressing two distinct test requirements: faster memory interfaces and the reliability of high-power devices. Its Magnum E2 memory tester, announced on 29 September, places digital instruments close to the device under test to limit signal degradation between the instrument and the chip. The platform targets advanced DRAM and NAND interfaces, including LPDDR6, DDR6 and GDDR7, and supports both engineering and production configurations.

Teradyne says the architecture supports NRZ, PAM3 and PAM4 signalling, with built-in logic-test capability alongside memory testing. Bringing the instruments nearer the device is intended to preserve the signal margins needed for testing at speed, while greater parallelism allows more devices to be tested together.

The Titan HP announcement on 6 October addressed thermal stress rather than interface speed. Instead of holding batches of devices in ovens at a controlled air temperature, the system controls each device's junction temperature while it runs a representative workload. Teradyne says this allows burn-in and system level test to run on the same platform, retaining an individual stress-and-test record for each device. Slots operate independently, so a long test in one does not leave the remaining slots waiting. The company described the enhanced burn-in system as already deployed in production.

Robotics also reached profitability and delivered its highest third-quarter revenue. Across the group, net income was $342.4 million.

For the fourth quarter, Teradyne forecasts revenue of $1.25 billion to $1.35 billion and GAAP earnings of $1.88 to $2.18 per diluted share.
