Semiconductor applied sciences reside and die by business requirements, however are there instances when it is smart to construct a closely personalized—even proprietary—reminiscence machine?
The chip sector is replete with requirements organizations that information the evolution of extensively adopted reminiscence units. JEDEC is answerable for DRAM, LPPDR, GDDR and high-bandwidth reminiscence (HBM), amongst others. The Peripheral Part Interconnect Categorical Particular Curiosity Group takes care of probably the most ubiquitous protocol for information motion, whereas NVMe Categorical and the CXL Consortium constructed their specs with PCIe as their basis. Most lately, the UCIe was developed to carry finest practices to chiplets.
Graham Allan, senior supervisor of product advertising and marketing at Synopsys, has been within the DRAM enterprise since 1985. “The freeway of DRAM applied sciences is suffering from the roadkill of non-JEDEC-standard reminiscences,” he mentioned. “If one thing isn’t JEDEC-standard, or if a DRAM vendor tries to go it alone with one thing that they need to differentiate with, it’s going to die.”
Among the many many deserted reminiscences that by no means noticed widespread use are Micron Know-how’s HBM competitor, Hybrid Reminiscence Dice, and Rambus’s virtual-channel DRAM, though the latter had the backing of Intel. “These items all die as a result of they don’t get pleasure from the whole ecosystem,” Allan mentioned.

He mentioned the worth of a standardized reminiscence machine is that it may be multi-sourced—an SK Hynix product will plug into the identical socket as a Micron product.
That’s to not say some distributors aren’t providing particular options, Allan famous. “There can be DRAM distributors that may have their very own particular options that they unlock for particular clients, and it’s nonetheless commonplace DRAM,” he mentioned. “You probably have the know-how below the hood to benefit from this little additional stuff that they put in there, that’s going to make the product all that significantly better.”
Sole-source eventualities put distributors in a nook
Some reminiscences which can be developed by a couple of vendor might present potential however are subsequently deserted by all however one of many distributors. Diminished-latency DRAM was initially developed by Infineon Applied sciences within the late Nineteen Nineties; Micron was subsequently introduced in as a improvement accomplice and a second supply, however Infineon opted to exit the market.
Allan mentioned the problem of being the only real supply of a reminiscence product that has a powerful buyer base—particularly if it’s a Tier 1 buyer—is that it’s troublesome to end-of-life the product. “Once you get just a few key design wins for one thing that’s a distinct segment, customized product that’s not commonplace, you get sucked into that vortex,” he mentioned.
The hazard to a vendor of being the one one to promote a reminiscence machine is that you just threat getting blacklisted by that buyer for a very long time in the event that they resolve to discontinue it, Allan added.
Jim Useful, principal analyst at Goal Evaluation, mentioned that there’s plenty of traits that may classify a reminiscence machine as proprietary—a DRAM that’s broad and slender to fulfill a buyer requirement, for instance. “That’s not unusual,” he mentioned.
How a reminiscence is packaged could make it proprietary, even when it’s a typical chip inside, Useful mentioned, as a result of it’s being utilized in a harsh setting, akin to deep-sea exploration.
Blurred strains between customized and proprietary
Useful famous that HBM began out as considerably proprietary—it was a reminiscence that SK Hynix made for AMD. He mentioned this doesn’t occur actually because one of many focal factors of reminiscences as a enterprise is that they’re an identical to one another. “That finally ends up making them so much cheaper, as a result of as a substitute of getting one thing that’s solely being purchased by AMD, you’ve obtained one thing that’s being purchased by AMD and 170 different firms,” he mentioned.
Useful mentioned it’s essential to differentiate between “customized” and “sole supply.” When it’s developed to buyer’s requests, it’s a customized reminiscence; sole supply is when the producer is the one producer of the product.
Both path goes to be costlier, and ideally, having the ability to purchase industrial off-the-shelf parts is most popular, even for specialised functions present in navy and aerospace sectors, as a result of utilizing a typical product is cheaper than a customized chip.
Customary reminiscences encourage an engineering ecosystem to be constructed round it, which implies clients have much less threat—if their most popular provider exits the marketplace for no matter purpose, they produce other choices.
Intel’s 3D Xpoint–primarily based Optane know-how required a substantial amount of engineering to implement. “Intel spent some huge cash making an attempt to make that occur,” Useful mentioned. Micron knew the know-how wasn’t worthwhile for Intel, which is why it by no means went to market with a 3D Xpoint SSD or DIMM. “If there have been a sufficiently big market, Samsung would have reverse-engineered the product and found out learn how to make one in every of their very own.”
Upfront threat can repay down the street
For Macronix Worldwide, an built-in machine producer within the nonvolatile reminiscence market, creating a proprietary product for a buyer may be well worth the threat in the long run if it results in excessive volumes and a long-term partnership.
In an unique interview with EE Instances, Macronix chairman and CEO Miin Wu mentioned he’s finally answerable for deciding if it is smart to offer a proprietary or extremely personalized product to a buyer with particular necessities. Except for the monetary reward if the upfront funding pays off, the work itself may be fairly rewarding for these engaged on a brand new product line.
Wu mentioned some functions and market segments usually tend to have customized necessities, which Macronix can resolve, akin to gaming and safety. Working with a buyer or accomplice on a customized design might not instantly seem like a high-volume enterprise alternative, however it could possibly open the door to future alternatives.
Macronix’s ArmorFlash know-how is an instance of a personalized product designed for a selected buyer alternative that gave beginning to a wider product class as a result of it addresses widespread safety challenges as extra units hook up with the web and are pushed out to the community edge.
Wu mentioned Macronix is targeted on creating new options within the market relatively than simply being one other provider competing with different distributors promoting comparable merchandise. “We’re creating our personal product; we’re creating our price,” he mentioned.
Any customized product that Macronix makes should meet high-quality requirements, Wu mentioned, and there must be robust indications that it’ll change into a high-volume enterprise. Sure functions elevate the chance that there are long-term advantages for taking a threat on a customized or proprietary product, akin to safety or aerospace, that may result in broader market alternatives, he mentioned, particularly in industries that require a excessive diploma of qualification for harsh environments with excessive temperatures.
Distinctive tasks drive innovation, expertise improvement
Partnerships with different firms, akin to Macronix’s relationship with Nvidia, are examples of how getting onboard early with a creating market can result in large payoffs—Wu famous that Nvidia has basically created a brand new market.
Taking the street much less traveled additionally permits Macronix and its staff to develop new skillsets that may be utilized to all elements of the enterprise. “If we create a challenge for our engineers to problem themselves, finally that may actually assist us to create protections in our future enterprise,” Wu mentioned.
Like Macronix, Phison has no real interest in being a “quick follower,” however the firm is discerning in relation to creating area of interest or proprietary merchandise.
In an unique interview with EE Instances, Phison CTO Sebastien Jean mentioned every part has caveats in relation to creating proprietary or closely personalized options for purchasers—and the road between them is blurry. “If you wish to really customise low-level signaling, overlook it,” he mentioned. “Nobody will make one thing that’s interoperable along with your machine until you’re Samsung and also you simply make all of the elements your self and also you’re promoting to your self.”
Jean mentioned making units that go towards requirements by swapping indicators and pins can actually trigger sparks—creating one thing proprietary shouldn’t be well worth the bother as a result of nothing finally ends up working collectively and clients get pissed off.
An instance of a really proprietary storage machine was Sony’s short-lived reminiscence stick, Jean mentioned, which had a novel kind issue that regarded so much like an SD card that was squished down and made longer. There have been no apparent advantages, he mentioned. “They have been doing that to lock individuals right into a kind issue so they might solely purchase them from a Sony. Form of like printer ink cartridges.”
Buyer vetting is crucial
Customization that leverages standards-based protocols does have worth, Jean mentioned, but it surely raises points round mental property (IP): “There’s a authorized distinction.” He mentioned clients coming to Phison realizing what modifications they need to personal the IP, but when Phison comes up with the answer, there’s a possibility to use it to different clients, even when it could possibly’t disclose particulars of the unique buyer engagement that sparked the concept.
The potential for top volumes is a consideration for Phison, however so is the boldness that the shopper can be round for the long term, Jean mentioned.
However whereas many large gamers will instantly flip down low-volume work, Phison will contemplate it by vetting the shopper and can finally cost for any non-recurring engineering (NRE), Jean mentioned. “It weeds out the individuals who ask for stuff and haven’t any actual plan to really make it actual or promote it, as a result of finally, we don’t earn a living off of the NRE,” he mentioned. “It covers the chance prices and it ensures engagement.”
These tasks must have government sponsorship from the shopper to reveal they’re critical, Jean mentioned. “In any other case, it is going to very probably die on the vine.” He mentioned if a buyer comes and asks for one thing and so they’re keen to pay for it, Phison will take it on if its engineering sources can be found and never tied up elsewhere.
Even when the work does go forward, it’s finally as much as the shopper to promote its product, Jean mentioned.
The good thing about taking over customized tasks, particularly from large gamers, may be worthwhile in a tight-knit business, he added, as phrase will get round that Phison is working with Tier 1 firms, which is sweet phrase of mouth and the corporate’s fame.
Finally, Phison should stay aggressive on its know-how path, Jean mentioned. “We additionally should be perceived as know-how innovators.”
