There are very few places on earth that are capable of producing the silicon wafers used in RAM. These factories are still producing at the same rate as before but buyers who pay more (large companies with data centers) are buying them so there are fewer left over for normal consumers (hence the high prices). So why not scale up by making the factories bigger or faster? They are, it will take decades to do that because the process is so advanced. Why not just scale out by building more factories for producing the parts? They are, but that too will take decades.
