yes to new processing/storage architectures
Editor:- December 12, 2017 - NGD Systems (formerly called NxGn Data) today published the results of a survey on the need for Intelligence storage for applications with large data sets.

The purpose of the study was to gauge whether the movement of large data sets across existing processing and storage architectures negatively impacts the cost and usability of the data by applications.

The results of the survey - Smart Storage Survey Report (pdf) - conducted by G2M Research for NGD - show that existing compute and storage architectures adversely impact the performance and cost of these applications, and that new architectures are needed if these applications are to continue to scale in size and capabilities.

NGD has been a pioneer of in-situ processing and their current approach is to leverage ARM processing cores within the SSD controller (although other types of implementation and tiering within the memory/ storage assets have been reported in these news pages from other researchers and developers).

Among other things the survey report says...

"Since the advent of digital computers, the IT industry has regularly oscillated between convergence and disaggregation, as well as how specific functionality has been packaged and delivered to those who use it. The movement of processing capabilities into storage media, as represented by in-situ processing in SSDs, represents a new evolutionary path in IT that has been made possible by the solid-state nature of SSDs." the article pdf)

Editor's comments:- 3 years ago I listed "in-situ SSD processing" as #1 of the 12 key SSD ideas which changed in 2014.

The implementations of this new architectural idea has had to adapt pragmatically to changes in the SSD market - notably the emergence of standards like NVMe and associated fabrics - but also to other technologies which have been introduced to enable memory systems to work better such as NVDIMMs, tiering software and rethinking the relative size and roles of memory compared to local storage (cloud adapted memory architecture).

do NVDIMMs pose new security risks?
DRAM remembers

The SSD market is moving into a new phase at the core of which is changed thinking about the role of memory and storage and software.
Where are we heading with memory systems and software?

Is more always better?
The ups and downs of capacitor hold up in 2.5" flash SSDs
If you could go back in time and take with you - in the custom DeLorean pickup - a factory full of modern memory chips and SSDs (along with backwards compatible adapters) what real impact would that have? Now - how about if you could come back to 2018 from the future? This thought experiment and analysis explains why we're seeing new memory accelerators which don't even look like memories.
are we ready for infinitely faster RAM?
(and what would it be worth)
Back in the early 1990s it was not uncommon to hear about specialist server companies which were using peltier effect heat sinks to refrigerate the fastest workstation processors so that they could be run at higher clock speeds... One of the biggest bottlenecks in the past decade has been RAM architecture and DRAM implementation itself.

Rambus and Xilinx partner on FPGA in DRAM array technology
Editor:- October 4, 2016 - Rambus today announced a license agreement with Xilinx that covers Rambus patented memory controller, SerDes and security technologies.

Rambus is also exploring the use of Xilinx FPGAs in its Smart Data Acceleration research program. The SDA - powered by an FPGA paired with 24 DIMMS - offers high DRAM memory densities and has potential uses as a CPU offload agent (in-situ memory computing).
Tezzaron expects to ship ReRAM SSDs in 2016
Editor:- January 23, 2015 - Tezzaron Semiconductor today announced it will use Rambus's ReRAM technology in forthcoming storage-class 3D memory devices for military, aerospace and commercial applications. The first of these designs is scheduled for production in 2016.
Rambus aims at replacement for flash SSDs
Editor:- February 13, 2012 - Rambus recently announced it has acquired Unity Semiconductor for an aggregate of $35 million in cash.

As part of this acquisition, the Unity team members have joined Rambus to continue developing innovations and solutions for next-generation non-volatile memory.

With 9 years of development history, Unity's memory technology, CMOx, has been designed to accelerate the commercialization of the Terabit generation of non-volatile memories. Unity expects that devices using CMOx cell technology will (one day) achieve higher density, faster performance, lower manufacturing costs and greater data reliability than NAND Flash.

"At Rambus, we are creating disruptive technologies to enable future electronic products," said Sharon Holt, senior VP and GM of the Semiconductor Business Group at Rambus. "With the addition of Unity, we can develop non-volatile memory solutions that will advance semiconductor scaling beyond the limits of today's NAND technology. This will enable new memory architectures that help meet ever-increasing consumer demands."
