Core Insights - DDR4 memory prices have doubled in the past two months due to supply shortages, with 8GB DDR4-3200 chips now exceeding $5, up from $1.75 earlier this year [1] - Smaller manufacturers are starting to ramp up DDR4 production in response to rising prices, while larger manufacturers like Micron are unlikely to follow suit as they focus on DDR5 and HBM production [1] - The overall DDR4 memory market is expected to stabilize once smaller manufacturers resume production, but a return to previous price levels may take time [2] Group 1 - Major DRAM manufacturers, including Micron, Samsung, and SK Hynix, have announced plans to cease DDR4 production by the end of 2025, contributing to the price surge [1] - Nanya Technology, a Taiwanese memory manufacturer, is benefiting from the price increase due to its extensive DDR4 product lineup and limited DDR5 offerings [1] - The demand for HBM chips driven by the growth of artificial intelligence is causing major manufacturers to shift their production focus away from DDR4 [2] Group 2 - The DDR5 standard was officially introduced by JEDEC in 2020, and while Intel's latest CPUs support both DDR4 and DDR5, AMD's Zen 4 and later processors only support DDR5 [2] - Despite the transition to newer technologies, the widespread use of DDR4 in existing systems means that the technology will not disappear immediately [2]
