DDR 4，风云突变

Core Viewpoint - Samsung has postponed its plan to stop supplying DDR4 DRAM until the end of 2026, which may disrupt the current market dynamics and affect Taiwanese DRAM manufacturers like Nanya Technology and Winbond [2][3]. Group 1: Market Dynamics - The expectation of major manufacturers exiting the DDR4 market had previously driven up spot prices, with DDR4 prices even surpassing DDR5 prices, creating a significant price inversion [2][3]. - TrendForce reported that the contract price for PC DDR4 8Gb reached $3.9 in late July, a 50% increase from June, while the 8GB module price rose to $26.5, exceeding DDR5's $25.5 [3]. Group 2: Impact on Taiwanese Manufacturers - Taiwanese manufacturers were optimistic about the rising DDR4 prices, which could help improve their financial performance; however, Samsung's continued production may disrupt this trend [3]. - Nanya Technology has been supplying 8Gb DDR4 products and anticipated continued price increases, which could positively impact its gross margin [3]. Group 3: Supply Chain and Pricing Pressure - Adata noted that DDR4 inventory levels were low, and demand was recovering, leading to improved revenue in the second half of the year [4]. - Despite some customers reducing orders, the overall supply-demand balance remains tight, particularly for high-capacity DDR5 products, which has led to price increases for DDR5 memory modules [4][5]. Group 4: Transition to DDR5 - There is a psychological expectation among server customers to transition to DDR5, although the associated costs for platform upgrades and custom materials pose significant challenges [5].
