三星、SK海力士、美光退出，下游抢囤促提价

Core Viewpoint - The recent price increase in DDR4 and LPDDR4x memory is primarily driven by supply constraints due to major manufacturers exiting the DDR4 market to focus on higher-margin products like DDR5 and HBM [1][3][4]. Group 1: Price Trends - DDR4 prices have surged significantly, with the price of 8GB DDR4 3200MHz modules rising from $1.63 at the beginning of the year to $5.1, an increase of over 200% [2]. - The price of 16GB DDR4 3200MHz modules has exceeded $12.8, reflecting a 260% increase since the start of the year [2]. - As of July 5, the average price for DDR4 16Gb (1Gx16) reached $16, making it 2.6 times more expensive than DDR5, marking the largest generational price gap in DRAM history [1]. Group 2: Supply Dynamics - Major manufacturers like Samsung, SK Hynix, and Micron have announced strategic exits from DDR4 production, with plans to cease production by early 2026 [1][3]. - The exit of these suppliers has led to a tightening of supply, causing prices to rise as downstream customers rush to stock up [3][4]. - Despite concerns over rising prices, manufacturers continue to procure memory due to inventory considerations, further driving up prices [3]. Group 3: Market Outlook - The current round of production halts is mainly focused on consumer-grade products, while supply for automotive, industrial, and network communication sectors will be maintained [4]. - Analysts predict that DDR4 prices may peak and then decline in the fourth quarter as suppliers begin to release inventory [4]. - Domestic manufacturers are expanding DDR4 production to fill the supply gap left by international firms, with companies like Dongxin and Beijing Junzheng optimizing their production lines [6][7]. Group 4: Industry Sentiment - The overall sentiment in the storage industry is positive, with expectations of improved demand in sectors like network communication and consumer electronics in the second half of the year [7].
