Core Viewpoint - The memory market is experiencing a significant price surge, with some products seeing price increases of up to three times since April 2023, driven by supply shortages and rising demand from AI infrastructure investments [1][2][4].

Supply Chain Adjustments - Major memory manufacturers such as SK Hynix, Samsung, and Micron are prioritizing high-margin products and reducing production of lower-margin items like DDR4 [6]. - The current price increase cycle is expected to last until supply and demand reach equilibrium, potentially extending for 1 to 2 years [6]. Impact on Consumer Electronics - The rising prices of memory products are affecting the costs of consumer electronics, leading to increased prices for assembled computers and smartphones [7]. - For instance, the price of the Redmi K90 series smartphones has increased significantly due to higher storage costs, with some models seeing price hikes of up to 600 yuan [7]. - Companies like Xiaomi have publicly acknowledged the impact of rising memory costs on their pricing strategies [7].
