Not sure how you're taking on Samsung or Micron when both of them have pulled out of the market...?
Micron hasn't pulled out of the market CXMT is in. They make DRAM chips, same as CXMT. They might also make DIMMs for servers and so on, but CXMT is primarily competing with the DRAM chip stuff.
Micron pulled out of the consumer market, they're still making DRAM.
There's been no news on Samsung exiting any DRAM market as far as I can tell?
