Gamingdeputy News on March 28, Introspect Technology announced the launch of the world's first GDDR7 video memory test system, supporting massive parallel, 72-channel, 40 Gbps PAM3 ATE-on-Bench testing.Claimed to provide the fastest time to market for video memory and GPU manufacturers.
Introspect has delivered the M5512 GDDR7 video memory test system, which it claims is the world's first commercial solution for testing JEDEC's new JESD239 Graphics Double Data Rate (GDDR7) SGRAM specification.

The system enables graphics memory engineers, GPU design engineers, product engineers in the memory and GPU space, and system integrators to quickly spin up new GDDR7 memory devices, debug protocol errors, characterize signal integrity, and perform detailed stress on memory read/write functions Test without 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.Up to 192 GB/s per device.
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. By using 3 levels (+1, 0, -1) to transmit 3 bits on 2 cycles, whereas the traditional NRZ (non-return to zero) interface transmits 2 bits on 2 cycles,PAM3 provides higher data transfer rates per cyclethereby improving performance.
The M5512 GDDR7 Video 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 the Samsung Semiconductor official website, reaching 28Gbps/32Gbps speeds respectively, and 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. Gamingdeputy friends can look forward to follow-up news.
