But to your point, that is exactly how American companies like to play now. No one is stopping them from screwing over the consumer.
I have a Micron near me and they are building another chip facility but we are years away still so I suspect China will beat them to the punch.
SK Hynix and Samsung are South Korean.
The Korean memory makers are playing the same game as Micron and simply moving existing capacity up-market.
GP was referring to upstart Chinese memory manufacturers like ChangXin, who - if their yields manage to catch the wave - could not have asked for a more favorable market after the big 3 have abandoned the consumer market. Consumers who would have otherwise turned up their noses at CXMT will not have the luxury.
Basically:
China floods the market with cheaper but less QA'd parts, makes a gazillion dollars, is able to spend said money to fix yields / QA issues and streamline operations, by the time that happens Micron and maybe a few other existing players will have new memory production, and then we'll have a flood of cheap, reliable memory. 4yr, maybe?
Memory in particular ... https://en.wikipedia.org/wiki/DRAM_price_fixing_scandal
The entry-cost to getting into memory is on the order of $billions and years - you can do just about anything...
If it costs you $1B and five years to build out new supply and you think demand will not sustain for more than three years, it does not make sense to expand supply.
Instead you will maintain your margins currently and await demand to decrease back to your current supply.
This is pretty common and as others have pointed out is even more common in markets where competition is slow and lead times are long.
Ammunition is a great example over the last decade or so as political turnover caused relatively short lived demand spikes and manufacturers didn't expand supply because they knew once political winds shift, demand would decrease.
In the past when memory supply was short and then rebounded, many companies went out of business because making memory was no longer profitable.
The thing is they tend to only do that when they can get a technological competitive advantage. The priority access gives them a locked in competitive edge, for a while. It’s not clear there is an opportunity like that in memory.
