Memory chip prices could tumble next year and end the "super cycle" of rising prices that started in mid-2016. TrendForce's DRAMeXchange estimates that NAND prices will fall 10% sequentially in the third and fourth quarters of 2018 before falling further in 2019. The firm also expects DRAM prices to tumble 25% next year.These declines were expected because the memory market is a cyclical, alternating between periods of shortage and surplus.
