NAND
Following an ongoing slump in demand that has impacted the entire memory industry over the last several months, Samsung this week has become the latest memory foundry to announce production cuts for NAND and DRAM. The "meaningful" cuts planned by Samsung make it the latest memory fab – and last of the big three – to undertake cuts in light of a significantly weaker market, while also marking an end to Samsung's efforts hold off on production cuts amidst the current slump to try to gain market share.
