Samsung Mass-producing First 128GB DDR4 RDIMM for Servers

 

Samsung Electronics Co., Ltd., announced today that it is mass producing the industry's first "through silicon via" (TSV) double data rate-4 (DDR4) memory in 128-gigabyte (GB) modules, for enterprise servers and data centers. Following Samsung's introduction of the world-first 3D TSV DDR4 DRAM (64GB) in 2014, the company's new TSV registered dual inline memory module (RDIMM) marks another breakthrough that opens the door for ultra-high capacity memory at the enterprise level. Samsung's new TSV DRAM module boasts the largest capacity and the highest energy efficiency of any DRAM modules today, while operating at high speed and demonstrating excellent reliability.

 

       We are pleased that volume production of our high speed, low-power 128GB TSV DRAM module will enable our global IT customers and partners to launch a new generation of enterprise solutions with dramatically improved efficiency and scalability for their investment," said Joo Sun Choi, executive vice president, Memory Sales and Marketing, Samsung Electronics. "We will continue to expand our technical cooperation with global leaders in servers, consumer electronics and emerging markets, where consumers can benefit from innovative technology that enhances their productivity and the overall user experience.

The 128GB TSV DDR4 RDIMM is comprised of a total of 144 DDR4 chips, arranged into 36 4GB DRAM packages, each containing four 20-nanometer (nm)-based 8-gigabit (Gb) chips assembled with cutting-edge TSV packaging technology.

Conventional chip packages interconnect die stacks using wire bonding, whereas in TSV packages, the chip dies are ground down to a few dozen micrometers, pierced with hundreds of fine holes and vertically connected by electrodes passing through the holes, allowing for a significant boost in signal transmission. In addition to capitalizing on the industry's highest capacity and TSV's advanced circuitry, Samsung's 128GB TSV DDR4 module has a special design through which the master chip of each 4GB package embeds the data buffer function to optimize module performance and power consumption.

As a result, Samsung's advanced 128GB TSV DDR4 RDIMM provides a low-power solution for next-generation servers with speeds at up to 2,400 megabits per second (Mbps), achieving nearly twice the performance, while cutting power usage by 50 percent, compared to using the previous highest capacity DRAM modules ? 64GB LRDIMMs, whose four-chip package stacks are hampered by power and speed limitations caused by their use of conventional wire bonding.

Samsung is responding to growing demand for ultra-high capacity DRAM by accelerating production of TSV technology in the market and quickly ramping up 20nm 8Gb DRAM chips to improve manufacturing productivity. In solidifying its technology leadership and expanding the market for premium memory solutions, the company plans to provide a complete lineup of its new high-performance TSV DRAM modules within the next several weeks including 128GB load reduced DIMMs (LRDIMMs).

In addition, Samsung will continue to maintain its technology leadership by introducing TSV DRAM with higher performance. These will include modules with data transfer speeds of up to 2,667Mbps and 3,200Mbps that help to meet intensifying enterprise server needs, while expanding TSV applications into high bandwidth memory (HBM) and consumer products.

 

My Thoughts

Capacity per DIMM is something that is constantly improving, allowing system builders the world over to build PCs with ever larger amounts of memory inside. 

128GB on a single DIMM is astounding, especially since most of us mainstream/consumer PC market are currently using 2GB, 4GB or 8GB DIMMS. Over time we will be using faster and larger capacity memory, but right Samsung are pushing the boundaries of exactly how much capacity can be place on a single DIMM of memory. It will certainly be a long time before memory of this capacity will make it's way into the consumer space, as right now even the most demanding games do not recommend more than 16GB of memory. 

I wonder how long it will be until systems need 128GB of system RAM or many chrome tabs would be required to fill it right now?

Meanwhile I'm only on 16GB with two sticks... Samsung really is going to town on the memory business.Quote
