Better Artificial Intelligence (AI) Memory Buy: Micron Technology vs. Sandisk After the July 2026 Sell-off

Both Micron Technology and Sandisk experienced significant sell-offs in July 2026 after strong first-half performance, with Micron down 20% and Sandisk down over 35%. Despite the sharp declines, both memory chip manufacturers benefit from AI data center demand. Micron is recommended as the better buy due to its exposure to both DRAM and NAND markets, lower forward valuation, and management guidance suggesting market tightness extending beyond 2027.
