• Memory Technologies: DRAM, HBM, GDDR, and the Scaling Wall · 2025-08-10

  Inside the memory hierarchy that feeds the compute engines — DRAM cell physics, HBM stack architecture, GDDR for graphics, the row hammer crisis, and emerging alternatives like FeRAM and MRAM.

• Processing-in-Memory: UPMEM, Samsung HBM-PIM, and the Near-Data Computing Paradigm · 2025-02-10

  How moving compute to where the bits live rewrites the rules of memory-bound computation, from UPMEM's DRAM-scale PIM to Samsung's HBM-PIM and the programming model that still keeps us up at night.
