Instrospect launches world's first GDDR7 graphics memory test system

According to news from this website on March 28, Introspect Technology announced the launch of the world's first GDDR7 video memory test system, which supports large-scale parallel, 72-channel, 40 Gbps PAM3 ATE-on-Bench testing. It is said to be able to test both video memory and GPU. Manufacturer provides fastest time to market.

Introspect has delivered the M5512 GDDR7 video memory test system, which it claims is the world’s first commercial test system for testing JEDEC’s new JESD239 graphics double data rate (GDDR7) SGRAM specification. solution.

The system enables graphics memory engineers, GPU design engineers, product engineers in the memory and GPU fields, and system integrators to quickly spin up new GDDR7 memory devices, debug protocol errors, characterize signal integrity, and perform detailed Stress test graphics memory read/write capabilities without the need for any other tools.

The Solid State Technology Association JEDEC officially released the JESD239 GDDR7 video memory standard on March 6. JESD239 GDDR7 provides twice the bandwidth of GDDR6, each device can reach up to 192 GB/s.

JESD239 GDDR7 is the first JEDEC standard DRAM to use the Pulse Amplitude Modulation (PAM) interface for high-frequency operation. Its PAM3 interface improves signal-to-noise ratio (SNR) for high-frequency operation while improving energy efficiency. PAM3 provides more High data transfer rate per cycle , thus improving performance.

The M5512 GDDR7 Memory Test System is a benchtop test and measurement instrument that 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 complete set of analog representation functions.

AMD, Micron, Nvidia, Samsung, and SK Hynix have all expressed support for the GDDR7 standard. After Samsung demonstrated GDDR7 video memory at the NVIDIA GTC 2024 conference, two video memory chips, model numbers K4VAF325ZC-SC32 and K4VAF325ZC-SC28, are now available on Samsung Semiconductor’s official website, reaching 28Gbps/32Gbps speeds respectively, with a single chip capacity of 16Gb.

SK Hynix said it is developing faster graphics memory modules, targeting a higher 40Gbps.

The NVIDIA RTX 50 series graphics cards, which are expected to be launched at the end of the year, will be the first products to use GDDR7 video memory. Friends on this site can look forward to follow-up news.
