Introspect Technology ships world’s first GDDR7 memory test system

Introspect Technology, a JEDEC® member and a leading manufacturer of test and measurement instruments, announced today that it has shipped the M5512 GDDR7 Memory Test System, the world’s first commercial solution for testing JEDEC’s newly minted JESD239 Graphics Double Data Rate (GDDR7) SGRAM specification. This category-creating solution enables graphics memory engineers, GPU design engineers, product engineers in both memory and GPU spaces, and system integrators to rapidly bring up new GDDR7 memory devices, debug protocol errors, characterize signal integrity, and perform detailed memory read/write functional stress testing without requiring any other tool.

The GDDR7 specification is the latest industry standard that is aimed at the creation of high-bandwidth and high-capacity memory implementations for graphics processing, artificial intelligence (AI), and AI-intensive networking. Featuring pulse-amplitude modulation (PAM) and an improved signal to noise ratio compared to other PAM4 standards used in networking, the GDDR7 PAM3 modulation technology achieves greater power-efficiency while significantly increasing data transmission bandwidth over constrained electrical channels.

“In its quest to support the industry on GDDR7 deployment, Introspect Technology has worked tirelessly in the last few years with JEDEC members to develop the M5512 GDDR7 Memory Test System,” said Dr. Mohamed Hafed, CEO at Introspect Technology. “Throughout our existence, we’ve thrived on creating unique test solutions for equally unique high-speed interface standards, and the GDDR7 standard is definitely unique! Introspect is thrilled to be part of the ecosystem supporting such a transformative technology,” he continued.

The M5512 GDDR7 Memory Test System is a bench-top test and measurement instrument that builds on Introspect Technology’s decades long experience in building high-performance and miniature test instruments. It contains 72 high-performance pins, each capable of operating at 40 Gbps in PAM3 mode. Each pin contains bidirectional circuitry for performing read and write operations, and each pin contains a full-suite of analog characterization features such as femto-second resolution skew injection, millivolt resolution voltage control, programmable jitter injection, and other eye margining features that are critical for AC characterization and conformance testing. The system also includes integrated device power supplies with precision power sequencing and ramping controls. This makes the M5512 an all-inclusive solution that can perform both AC characterization as well as memory functional stress testing on any GDDR7 device. Additionally, by leveraging the highly flexible Pinetree environment, the M5512 can be deployed for GDDR7 memory controller testing and memory PHY testing as well.

The M5512 GDDR7 Memory Test System is part of Introspect Technology’s emerging M Series product line, a series of massively parallel products for testing high data rate, high channel count devices and systems.
