Driven by such factors as the continued development of autonomous driving technologies and the build-out of 5G infrastructure, the demand for automotive memories will undergo a rapid growth going forward, according to TrendForce's latest investigations. Take Tesla, which is the automotive industry leader in the application of autonomous vehicle technologies, as an example. Tesla has adopted GDDR5 DRAM products from the Model S and X onward because it has also adopted Nvidia's solutions for CPU and GPU. The GDDR5 series had the highest bandwidth at the time to complement these processors. The DRAM content has therefore reached at least 8 GB for vehicles across all model series under Tesla. The Model 3 is further equipped with 14 GB of DRAM, and the next-generation of Tesla vehicles will have 20 GB. If content per box is used as a reference for comparison, then Tesla far surpasses manufacturers of PCs and smartphones in DRAM consumption. TrendForce forecasts that the average DRAM content of cars will continue to grow in the next three years, with a CAGR of more than 30% for the period.



Based on the existing vehicle models circulating in the global car market, TrendForce estimates that the average DRAM content of cars will reach around 4 GB in 2021. The growth in the average DRAM content of cars is expected to be much higher this year than in the past few years. However, car sales are not as great in scale when compared with sales of consumer electronics such as notebook (laptop) computers and smartphones. In 2019 before the COVID-19 pandemic, the annual global car sales totaled around 94 million vehicle units. Also, cars have less DRAM content compared with servers. Looking at the 2019 data, the distribution of the annual global DRAM consumption shows that the automotive memory segment accounted for less than 2% of the total.

Despite high barrier to entry, memory suppliers have been scrambling for automotive market share due to high profit margins
Compared with other application segments, automotive memory has a much higher standard for durability and reliability over the long term. The operating lifecycle of a car starts at 10 years, so DRAM suppliers basically have to guarantee that their automotive memory solutions have a product lifecycle of at least 7-10 years in order to satisfy the needs related to vehicle maintenance and replacements of parts. From the perspective of suppliers, the selection of process technology for product development and manufacturing is a key decision point when it comes to formulating a strategy for the automotive memory segment. Even as suppliers continuously migrate to the more advanced process technology, they have to ensure product longevity and long-term support for their automotive offerings.

Another issue, which is associated with durability, is operating temperature. Given that countries around the world have their own climates and extreme weather events, automotive DRAM products must have a much wider temperature range with a higher threshold and a lower threshold when compared with other categories of DRAM products, in order to ensure that cars do not break down on the road. Finally, with density and other specifications being the same, prices of automotive DRAM products are at least 30% higher than prices of conventional commercial DRAM products. For the automotive DRAM products that have met some of the most stringent standards set by the industry, their prices can even be several times higher than prices of conventional commercial DRAM products. In sum, although automotive DRAM products are more difficult and costly to manufacture than other kinds of DRAM products, their high profit margins and large potential market have been attracting DRAM suppliers to now scramble for a piece of the automotive memory segment.

Taiwanese manufacturers show great potential as Winbond thrives in automotive OEM market with its comprehensive product portfolio
Currently, Micron is the leader in automotive memory products with a market share of nearly 50%. The supplier first has the geographical advantage. Moreover, its collaborative relationships with tier-1 automotive suppliers based in Europe and the U.S. are longer in duration compared with its competitors. Micron also has a more comprehensive product lineup for automotive applications, ranging from traditional solutions (e.g., DDR2 to DDR4) to LPDDR solutions (e.g., LPDDR2 to LPDDR5) to GDDR6 solutions. Additionally, Micron provides automakers with other types of memory technologies such as NAND Flash, NOR Flash, and MCP.

Apart from the three dominant DRAM manufacturers, Taiwan-based Nanya Tech and Winbond are continuing to release a wide variety of memory products in response to the growing demand of the automotive industry. In addition to possessing a comprehensive product mix ranging from traditional DDR solutions (e.g., up to DDR4) to low-power solutions (e.g., LPSDR to LPDDR4X), Nanya Tech has also adopted the 20 nm node for a significant portion of its manufacturing processes, which are relatively stable in terms of yield rate. On the whole, automotive applications account for nearly 15% of Nanya Tech's specialty DRAM revenue, while specialty DRAMs account for more than 60% of the company's total revenue.

Winbond, on the other hand, has been cultivating its presence in the automotive market for more than 10 years. Although the three dominant DRAM manufacturers are ahead of Winbond in terms of process technologies, Winbond's extensive product portfolio, which includes specialty DRAM, mobile DRAM, NOR Flash, SLC NAND, and MCP, represents a competitive advantage over the vast majority of other manufacturers. Given that the automotive OEM market is both relatively stable and profitable, Winbond has been placing a long-term focus on this market; automotive applications now comprise more than 10% of the company's total memory revenue, and Winbond's automotive business will likely continue to expand going forward.

Let me point to a comment below one of the recent TrendForce press releases.
You can be suspicious of anything, if you're so inclined. But power outages aren't that uncommon.

Customers that pay $20,000-30,000 where they used to pay $10,000 or so? Cars that last 7-10 years where they used to last 30?

Inflation was made to make everyone poor eventually, change my mind.

Inflation is only part of the equation and quite unavoidable at that.
But surely nobody thought manufacturers will pay for implementing various regulations out of their own pocket.

Poverty is a side effect, inflation is meant to deter big investor from holding onto cash instead of continuing to invest it further to keep up demand for ever increasing economical growth.

Inflation is not meant. Period.
If kept in check, one of it better side effects is exactly what you said, that much is undeniably true.

But it's not like inflation was invented by anyone (much less for a given purpose). Inflation was born when the guy looking to swap his grain for goats saw the other guy had more goats than he did last year and decided to ask for more goats in return for the same amount of grain. It's a natural evolution of the free market.

It's saddening to see Winbond fail at their DDR4 plans (yes there were some)
Means fewer players...

The request for sensorics in the cars from OEMs is on the rise.
They are adding multiple cameras, radars, etc to cars to do stuff like surround view, park assists, automatic parking, cruise control, active lane assist and autonomous driving is also seems to be very hot topic at OEMs etc.
All these systems require multiple control units. The heart of these is usually some SoC, DDR, Flash, Ethernet etc.
Features which some years ago existed in premiun car models are coming to mainstream cars.
This is increasing demand of these components.

I personally still an old style guy who does not like to give control of my vehicle to the electronics.
I like to drive and park my car myself and not be dependent on the electronic systems except for maps for navigation and Bluetooth to connect my phone. :p
