Teradyne Expands Memory Test Portfolio: Can It Beat KLAC & COHU?
Teradyne TER is benefiting from rising demand for advanced memory testing, supported by strong high-bandwidth memory (HBM), DRAM, and NAND requirements tied to artificial intelligence (AI) infrastructure. The company’s expanding memory test portfolio, led by Magnum platforms, strengthens its competitive positioning in the broader semiconductor test-equipment market against KLA KLAC and Cohu COHU. Teradyne noted that Magnum testers combine memory and logic-test capabilities, providing memory manufacturers with attractive swing-tool flexibility.
Memory has emerged as an important growth engine for Teradyne. In the second quarter of 2026, memory revenues reached a record $212 million, marking the third consecutive quarter above $200 million. Growth was driven by robust demand for HBM and DRAM test solutions, as well as a recovery in NAND. Memory book-to-bill exceeded 2, indicating solid demand visibility. Management expects the 2026 memory test TAM to be more than 40% higher than 2025, supported by HBM, DRAM and NAND growth.
Further expanding its memory test portfolio, Teradyne recently launched Magnum E2, a next-generation high-speed memory test system designed to address growing test requirements driven by artificial intelligence and high-performance computing. Built on the company’s Near-DUT Test architecture, Magnum E2 supports advanced DRAM and flash interfaces, including LPDDR6, DDR6, GDDR7 and NAND flash. The platform offers higher parallelism, improved signal integrity and support for NRZ, PAM3 and PAM4 signaling. It also combines memory and logic testing on a single platform, helping manufacturers simplify testing while supporting qualification through high-volume production.
Rising memory bit production and technology transitions such as HBM3 to HBM4, DDR5 to DDR6 and next-generation flash should further increase test requirements, supporting Teradyne’s ability to expand its memory-testing footprint. Management expects memory revenues to grow in the second half compared to the first half.
How Competitors Fare Against TER
Teradyne is facing stiff competition from companies such as KLA and Cohu. Both companies are expanding their footprint in the semiconductor industry.
KLA is benefiting from strong semiconductor demand, driven by accelerating investments in AI infrastructure, leading-edge foundry/logic, memory and advanced packaging. In the fourth quarter of fiscal 2026, revenues reached a record $3.66 billion, increasing 15% year over year and 7% sequentially. Management attributed the performance to rising AI infrastructure investments and greater process-control intensity across memory and advanced packaging.
Cohu’s improving semiconductor test demand and expanding exposure to AI computing, HBM inspection and software remain noteworthy. Growth in AI workloads is driving demand for HBM, and Cohu has established a position in this market through its Neon inspection platform. Cohu is extending its Neon inspection platform across HBM3, HBM4 and HBM4E production while investing in HBM5 and later generations.
