According to DRAMeXchange, a division of global research firm TrendForce, in addition to NAND flash capacity adjustments due to the fire at SK Hynix, NAND flash vendors were overly optimistic towards OEM demand in the fourth quarter, resulting in supply that exceeded demand for the quarter. As such, NAND flash brand suppliers’ revenue fell to US$6.168 billion in the fourth quarter of 2013, a 4.5% drop from the previous quarter, but a 16% increase over the same period in 2012. As advanced technology improves yield rates, the NAND flash industry will continue to experience steady growth.
