We observe Samsung and select rivals leading in advanced DRAM production down to ~10-15 nanometers line width – thinner than a virus! Intel and Micron‘s Joint IM Flash venture currently trails in NAND process maturity yet holds potential to someday claim DRAM leadership too.
Notably Taiwan‘s two smallest players exhibit big ambitions – with Nanya gearing up for cutting-edge EUV-based production and niche expert Winbond uniquely positioned to drive emerging memory types.
As process complexity increases however, so too do fabrication costs along with technological uncertainty from attempting to pattern device features smaller than wavelengths of light!
Next we’ll explore crucial strategic dynamics around this persistent industry pressure.
Economics and Outlook
Expanding production capacity requires massive capital investment, incentivizing consolidation like Intel and Micron‘s IM Flash joint venture. Yet despite periodic gluts, bit demand growth has mostly kept pace as shown above. Annual DRAM revenue could approach $300 billion by 2030.
With memory chips as ubiquitous building blocks inside all electronics however, their commodity economics also carry geostrategic implications. Governments recognize DRAM and NAND technology as critically impacting computing capabilities, communications infrastructure, industrial automation, defense systems and more.
Unsurprisingly therefore, national industrial policies support domestic semiconductor firms through subsidies, protectionist trade measures and import/export controls. Yet this fragmentation counterproductively steers R&D budgets towards proprietary IP over pre-competitive basic research.
Within such a climate, the "free agent" memory makers of Taiwan and Korea seem best positioned to drive relentless innovation. Giant Samsung also faces pressure to open some intellectual property.
Bilateral partnerships around high-cost production like Intel and Micron‘s could accelerate technology development and firm scale. With equipment expenses now topping product prices, such "co-opetition" may increasingly make sense to mitigate investment risks.
Meanwhile, rising ecological consciousness also compels energy conservation and carbon footprint reductions. So while physics constraints to Moore‘s Law loom, we find no shortage of commercial and social motivations to discover creative breakthroughs!
The future remains dynamic indeed.
