Better Memory Stock to Buy: Micron or SanDisk?

Most investors would beryllium precise blessed if a banal they owned quadrupled implicit 10 years. But they'd apt beryllium ecstatic if the banal alternatively delivered specified a immense summation implicit 12 months.

Micron makes aggregate types of memory, including dynamic random-access representation (DRAM), NAND flash memory, and high-bandwidth representation (HBM). It continues to beryllium highly palmy connected each fronts.

The institution generated grounds DRAM gross of $10.8 cardinal successful the archetypal 4th of 2026, up 69% twelvemonth implicit twelvemonth and 20% 4th implicit quarter. Micron can't marque capable DRAM chips to support up with demand. It's a akin communicative with NAND flash memory. Micron reported Q1 NAND gross of $2.7 billion, a 22% year-over-year and sequential increase. Again, request is importantly outpacing supply.

Micron's HBM accidental is adjacent much impressive. The institution has wholly sold retired of HBM supplies for 2026. It expects the full addressable marketplace for HBM to summation astatine a compound yearly maturation complaint of astir 40% done 2028, reaching $100 billion. HBM is captious for AI chips.

This debased valuation is chiefly owed to Micron's estimation arsenic a cyclical stock. But the existent upward rhythm successful representation seems apt to proceed for a while.
