Shares of Micron Technology (MU) fell about 2% on Monday following a report that Samsung Electronics (SSNLF) is nearing an Nvidia (NVDA) certification for its HBM4 AI memory chips.
Nvidia (NVDA) uses high-bandwidth memory, or HBM, chips for its AI accelerators. South Korean company SK hynix (HXSC.F) is a major supplier of HBM chips to Nvidia and competes with compatriot Samsung and American company Micron.
Driven by the demand from data centers and AI-related infrastructure, memory and storage makers have seen their stocks surge in the past one year.
Last week, Samsung reportedly noted that rumors were inaccurate that it implemented an 80% price increase across its memory products. Earlier this month, it was reported that Samsung and SK hynix are looking to raise prices for server memory by up to 70% in the first quarter, as a surging demand in AI impacts global supply. Samsung and SK hynix are among the largest memory chipmaking companies.
In November 2025, it was reported that memory suppliers like Samsung, SK hynix and Micron were already facing shortages of older dynamic RAM, or DRAM, products after reducing production to focus on HBM.
Other memory product-making companies like Sandisk (SNDK), Seagate Technology (STX), and Western Digital (WDC) have also seen their stocks soar. In the past one year, Western Digital’s stock has surged about 278%, while Seagate has jumped 235%. Shares of Sandisk, which was spun off from Western Digital in February last year, have skyrocketed around 1,037% in the past six months.
On Monday, Seagate’s stock jumped about 6%, Western Digital climbed around 3%, and Sandisk rose nearly 1%.
