RAM price surge sparks DIY memory builds and fuels shift to unified memory

Rising memory costs, driven by soaring AI workloads, have left PC builders searching for alternatives. In the United States, hobbyist Polymatt crafted a handcrafted USB stick using Apollo-era magnetic‑core memory, showcasing a low‑cost, though niche, solution to the premium‑priced DDR modules.

At the same time, Japanese manufacturers are promoting unified memory architectures that embed RAM directly inside the processor package. While this design promises higher bandwidth and lower latency for AI‑intensive tasks, it also threatens the traditional model of user‑upgradable RAM, potentially fixing memory capacity at purchase.
