ENGLISH OVERVIEW

Memory and storage

Prepared by IndustryAtlasEditorial principles & corrections

Chips, manufacturing, controllers and products

DRAM is working memory; HBM is a high-bandwidth DRAM architecture. NAND and NOR retain data without power. Distinguish chip vendors, foundries, assembly and test, controllers, and finished products.

Role and technical challenges

Nanya, Winbond and Macronix are IDMs in different product segments; ESMT and Etron design memory ICs. PSMC provides manufacturing, Phison provides NAND controllers and solutions, and ADATA and Transcend integrate modules and storage products.

Supply relationships and peers

Separate chip products from manufacturing services, then modules and finished products. The nine Taiwanese companies form a branched network.

  • PSMC provides manufacturing; ESMT, Etron, Nanya and Winbond can all supply DRAM products.
  • ADATA and Transcend DIMMs and SSDs have different inputs; on-board memory can reach system makers directly.
  • Phison E26 in ADATA LEGEND 970 is a documented product example, not evidence for other models or Transcend purchases.
