Hot Chips 2026: Samsung’s Processing-in-Memory (PIM)

In-memory compute has been an attractive proposition for many years because compute within a memory chip can exploit its higher internal bandwidth. Additionally, in-memory compute avoids the long latency path between DRAM and traditional compute cores. At Hot Chips 2026, Samsung discusses their continued pursuit of in-memory compute with their PIM (Processing-in-Memory) push. They’re implementing MAC units within LPDDR5X chips, while preserving the chip’s ability to interface with a standard mem...
