Global memory semiconductor shortages continued in September, pushing DRAM (short-term computer memory) and NAND flash (persistent storage memory) prices to record levels. DRAM’s average fixed transaction price for DDR4 8Gb 1Gx8 rose 4% from August to $26, extending its increase streak to 18 months. NAND flash pricing for 128Gb 16Gx8 MLC reached $30.61 after rising 0.44%, marking 21 consecutive months of gains since January 2025. The pace of DRAM increases has moderated after third-quarter contract negotiations reduced September transaction volumes, but TrendForce raised its fourth-quarter PC DRAM price forecast to 13%-18% from 3%-8% as suppliers shift capacity toward server memory. NAND’s fourth-quarter price is expected to remain flat as buyers face higher costs and limited capacity to absorb further increases. Industry participants expect a prolonged period of elevated prices rather than the 40% monthly surges seen in the past.
