Semiconductor applied sciences reside and die by trade requirements, however are there instances when it is smart to construct a closely personalized—even proprietary—reminiscence gadget?
The chip sector is replete with requirements organizations that information the evolution of extensively adopted reminiscence gadgets. JEDEC is liable for DRAM, LPPDR, GDDR and high-bandwidth reminiscence (HBM), amongst others. The Peripheral Element Interconnect Categorical Particular Curiosity Group takes care of essentially 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 convey greatest 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 affected by the roadkill of non-JEDEC-standard recollections,” he stated. “If one thing isn’t JEDEC-standard, or if a DRAM vendor tries to go it alone with one thing that they wish to differentiate with, it’s going to die.”
Among the many many deserted recollections that by no means noticed widespread use are Micron Expertise’s HBM competitor, Hybrid Reminiscence Dice, and Rambus’s virtual-channel DRAM, though the latter had the backing of Intel. “This stuff all die as a result of they don’t get pleasure from all the ecosystem,” Allan stated.

He stated the worth of a standardized reminiscence gadget 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 might be DRAM distributors that can have their very own particular options that they unlock for particular prospects, and it’s nonetheless customary DRAM,” he stated. “When you have the know-how beneath the hood to reap the benefits of this little additional stuff that they put in there, that’s going to make the product all that a lot better.”
Sole-source eventualities put distributors in a nook
Some recollections which might be developed by multiple vendor might present potential however are subsequently deserted by all however one of many distributors. Decreased-latency DRAM was initially developed by Infineon Applied sciences within the late Nineties; Micron was subsequently introduced in as a growth accomplice and a second supply, however Infineon opted to exit the market.
Allan stated the problem of being the only real supply of a reminiscence product that has a robust buyer base—particularly if it’s a Tier 1 buyer—is that it’s troublesome to end-of-life the product. “While you get a couple of key design wins for one thing that’s a distinct segment, customized product that’s not customary, you get sucked into that vortex,” he stated.
The hazard to a vendor of being the one one to promote a reminiscence gadget is that you simply danger getting blacklisted by that buyer for a very long time in the event that they resolve to discontinue it, Allan added.
Jim Helpful, principal analyst at Goal Evaluation, stated that there’s plenty of traits that may classify a reminiscence gadget as proprietary—a DRAM that’s vast and slender to satisfy a buyer requirement, for instance. “That’s not unusual,” he stated.
How a reminiscence is packaged could make it proprietary, even when it’s a typical chip inside, Helpful stated, as a result of it’s being utilized in a harsh setting, equivalent to deep-sea exploration.
Blurred strains between customized and proprietary
Helpful famous that HBM began out as considerably proprietary—it was a reminiscence that SK Hynix made for AMD. He stated this doesn’t occur actually because one of many focal factors of recollections as a enterprise is that they’re equivalent to one another. “That finally ends up making them rather a lot cheaper, as a result of as an alternative of getting one thing that’s solely being purchased by AMD, you’ve bought one thing that’s being purchased by AMD and 170 different firms,” he stated.
Helpful stated it’s necessary 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 business off-the-shelf parts is most well-liked, even for specialised purposes present in army and aerospace sectors, as a result of utilizing a typical product is cheaper than a customized chip.
Commonplace recollections encourage an engineering ecosystem to be constructed round it, which suggests prospects have much less danger—if their most well-liked provider exits the marketplace for no matter motive, they produce other choices.
Goal Evaluation’s Jim Helpful
Intel’s 3D Xpoint–primarily based Optane know-how required an excessive amount of engineering to implement. “Intel spent some huge cash attempting to make that occur,” Helpful stated. 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 discovered methods to make one in every of their very own.”
Upfront danger can repay down the street
For Macronix Worldwide, an built-in gadget producer within the nonvolatile reminiscence market, creating a proprietary product for a buyer could be definitely worth the danger in the long run if it results in excessive volumes and a long-term partnership.
In an unique interview with EE Occasions, Macronix chairman and CEO Miin Wu stated he’s finally liable 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 could be fairly rewarding for these engaged on a brand new product line.

Wu stated some purposes and market segments usually tend to have customized necessities, which Macronix can remedy, equivalent 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 particular buyer alternative that gave start to a wider product class as a result of it addresses frequent safety challenges as extra gadgets hook up with the web and are pushed out to the community edge.
Wu stated Macronix is targeted on creating new options within the market relatively than simply being one other provider competing with different distributors promoting related merchandise. “We’re creating our personal product; we’re creating our price,” he stated.
Any customized product that Macronix makes should meet high-quality requirements, Wu stated, and there must be sturdy indications that it’ll change into a high-volume enterprise. Sure purposes elevate the chance that there are long-term advantages for taking a danger on a customized or proprietary product, equivalent to safety or aerospace, that can result in broader market alternatives, he stated, particularly in industries that require a excessive diploma of qualification for harsh environments with excessive temperatures.

Distinctive initiatives drive innovation, expertise growth
Partnerships with different firms, equivalent 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 primarily 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 can actually assist us to create protections in our future enterprise,” Wu stated.
Like Macronix, Phison has little interest in being a “quick follower,” however the firm is discerning with regards to creating area of interest or proprietary merchandise.
In an unique interview with EE Occasions, Phison CTO Sebastien Jean stated every little thing has caveats with regards 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, neglect it,” he stated. “Nobody will make one thing that’s interoperable together with your gadget until you’re Samsung and also you simply make all of the elements your self and also you’re promoting to your self.”
Jean stated making gadgets that go in opposition to requirements by swapping alerts and pins can actually trigger sparks—creating one thing proprietary is just not definitely worth the hassle as a result of nothing finally ends up working collectively and prospects get annoyed.
An instance of a really proprietary storage gadget was Sony’s short-lived reminiscence stick, Jean stated, which had a singular type issue that appeared rather a lot like an SD card that was squished down and made longer. There have been no apparent advantages, he stated. “They had been doing that to lock individuals right into a type issue so they’d solely purchase them from a Sony. Form of like printer ink cartridges.”
Buyer vetting is important
Customization that leverages standards-based protocols does have worth, Jean stated, but it surely raises points round mental property (IP): “There’s a authorized distinction.” He stated prospects coming to Phison figuring out what modifications they wish to personal the IP, but when Phison comes up with the answer, there’s a chance to use it to different prospects, even when it could possibly’t disclose particulars of the unique buyer engagement that sparked the concept.
Phison’s Sebastien Jean
The potential for prime volumes is a consideration for Phison, however so is the arrogance that the client might be round for the long term, Jean stated.
However whereas many large gamers will instantly flip down low-volume work, Phison will think about it by vetting the client and can finally cost for any non-recurring engineering (NRE), Jean stated. “It weeds out the individuals who ask for stuff and don’t have any actual plan to really make it actual or promote it, as a result of finally, we don’t become profitable off of the NRE,” he stated. “It covers the chance prices and it ensures engagement.”
These initiatives must have govt sponsorship from the client to exhibit they’re severe, Jean stated. “In any other case, it is going to very seemingly die on the vine.” He stated if a buyer comes and asks for one thing they usually’re prepared to pay for it, Phison will take it on if its engineering sources can be found and never tied up someplace else.
Even when the work does go forward, it’s finally as much as the client to promote its product, Jean stated.
The advantage of taking up customized initiatives, particularly from large gamers, could be useful in a tight-knit trade, 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.
In the end, Phison should stay aggressive on its know-how path, Jean stated. “We additionally should be perceived as know-how innovators.”
