Adesto Technologies Launches IoTs Memory

Adesto-Logo

Sunnyvale, CA – Adesto Technologies is introducing an ultra-low power memory solution with the ability to aid in the design of Internet-of-Things (IoT) applications that can run for years on a single battery.

Adesto also announced that the new 45nm based CBRAM Products will be manufactured by TowerJazz Panasonic Semiconductor Company  (TPSCo), 300mm, Hokuriku, Japan Fab.

There’s much to like with their selection of “Moneta” for the branding name. Moneta is the goddess of memory and money – also prosperity and finances. In fact the English word “Money” derives from this lovely goddess’s name.

Adesto went public last October on the NASDAQ Exchange with the call letters IOTS, a straight forward play on the companies intentions. Long thought a takeover target by many analysts the company seems to have convinced acquisition suitors that they are much better off by leaving Adesto an independent entity – this gives the company the ability to adapt their Resistive Conductive-Bridging Random Access Memory (CBRAM) to a multiplicity of special design requirements for the rapidly expanding IoTs segment. Adesto, in effect, has been able to dodge the takeover bullet by being much more useful by remaining small while offering their products through multiple avenues from discrete devices through BEOL SoCs.

Adesto, having completed their developmental stage, is now transitioning to the commercialization and expansion phase of their technology. Several analysts expect that the company will continue to capture a significant portion of the non-volatile memory outside of the commodity data storage market and enjoy profitable royalty licensing from a number of other markets.

The newly introduced memory is entering “…, a hardware landscape (that) is changing quickly,” according to Narbeh Derhacobian, chief executive officer of Adesto. “Off the-shelf memory products were appropriate for the smartphone and PC markets, but they cannot satisfy the requirements of a new world of connected things. Unless we can dramatically reduce power consumption, the cost of changing batteries will prevent the IoT from becoming a reality. At Adesto, we are focused on this emerging market, and Moneta demonstrates our ability to execute and deliver next-generation products to meet its requirements.”

Adesto is a case book example of a company that has been “tinkering away” with a technology that the greater market paid little attention to. Gaining traction has been a continuing mantra of Adesto’s management. Along the way they gathered a number of “Black Swan Outliers” helping them to steer their way to, and carve out an unoccupied niche in the ultra-low power, non-volatile memory for the Internet-of-Things market – a market that is now enjoying a sudden and near explosive growth rate. Let us all remember that there is no such thing as an “easy” technology.

Viking Technology and Sony in ReRAM memory mashup

Viking-+-Sony-LogoViking Technology, a Sanmina Company, announced that it  is  collaborating with Sony Corporation to bring ReRAM Storage Class Memory to the NVDIMM market.

“Viking has a strong legacy developing Non-Volatile DIMM (NVDIMM) products over several generations from DDR2 to DDR4,” said Hamid Shokrgozar, President, Viking Technology. “This partnership with Sony solidifies a long term roadmap for our NVDIMM products by utilizing next generation ReRAM Storage Class Memory from Sony. This product roadmap is also very important for our customers, who are deploying this key technology in their next generation computing and storage products. It also sets the stage for future Persistent Memory module solutions not only for Viking but for the enterprise storage and server markets.”

According to the company’s announcement, “The collaboration between the companies launches a significant advance in Storage Class Memory system product development, designed specifically for enterprise computing customers. Sony ReRAM Storage Class Memory delivers performance and endurance that greatly exceeds NAND flash, while simultaneously providing the data non-volatility and module memory capacity desired for persistent applications”.

“We are excited and looking forward to the co-development with Viking Technology on the next generation of NVDIMM products,” said Terushi Shimizu, Senior Vice President and Deputy President of Device Solutions Business Group, Sony Corporation. “At this stage in ReRAM development, we are looking ahead to the implementation of this technology accelerating real-world cloud datacenter applications such as In-Memory Databases and Real Time Analytics. This will prove to be an exciting new chapter in the decade long development of our ReRAM memory technology.”

Non-Volatile DIMMs, often termed NVDIMMs, are designed to deliver high performance, endurance and reliability to next generation servers that are NVDIMM enabled. Traditionally, enterprise applications could not depend on main memory (DRAM) alone because it is volatile (loss of data upon power failure). Therefore, batteries, Uninterruptable Power Supplies (UPS’s) and techniques such as check-pointing have been used to ensure data durability, but at the cost of performance. NVDIMMs now enable server and storage arrays to utilize persistent memory that delivers both the highest performance and 100 percent data integrity.

The Coming out of ReRAM; a Resistive Memory Family Member

The real eye opener is the strange bedfellows that are making a sudden appearance in what can only be called the “Resistive Memory Rush”. Most in the analyst community expected such a forward thinking announcement to be coming from companies like Samsung, Toshiba and SK Hynix. That it came from Viking and Sony only makes sense if you’ve been immersed in the ruminations of the resistive universe for the last 15 years.

In discussions with Viking over the past several years I’ve asked about how they expected to position the company with the coming advent of In-Memory Database computing – this is their answer.

Of all the companies that have gone from memory modules to SSDs Viking is to date the only company to make the tie-up with a semiconductor supplier of resistive memory with the potential IMDB marketplace. Viking has set their strategy on supplying the IMDB marketplace with what might be called “Storage Class DIMMs” that support legacy DRAM with DDR4 stacked DRAMs coupled with Persistent Storage provided by Sony ReRAMs.

TechEye Take

This announcement, in no small way, adds further credence to the validation of resistive RAM as a key element in systems that will be announced in the next several days and should quiet the naysaying into obscurity.

The downside is the lack of numbers. Intel/Micron hasn’t provided any except comparison numbers but none that could be plugged into an Excel spreadsheet. Stay tuned…,
