Context Before

In this report, we will examine HBM’s present state, what’s happening in the supply chain, and the groundbreaking changes happening in the future. We’ll examine HBM’s critical role in AI accelerator architecture, the impact HBM is having on the DRAM market, and why it is upending the way memory market analysis is being performed. For subscribers, we will also address the major questions on Samsung’s future viability as a supplier, as well as highlight one technological change that may reverse the trend of increasing HBM capacity.

HBM Primer

Evidence

This significantly wider bus results in HBM being far superior in terms of bandwidth per package than any other form of memory.
