# RAM RAM (Random-Access Memory) is a device's fast, temporary working memory — the desk surface where the [[Central Processing Unit]] keeps whatever it is actively using right now. It is *volatile*: its contents vanish when power is cut, which is why unsaved work is lost in a crash. RAM is distinct from storage like a [[Solid-State Drive]], which keeps data permanently but is far slower; the standard analogy is RAM as the desk you work on, storage as the filing cabinet. More RAM lets a device juggle more programs and larger files at once. ## Why it matters here RAM is a genuinely neutral building block with little political cargo of its own — included here as foundational literacy and as a frequent point of confusion (people routinely conflate "memory" with "storage"). The one place it brushes the vault's concerns is the memory-chip industry itself: high-bandwidth memory (HBM) has become a bottleneck in AI accelerators, and memory fabrication is concentrated in South Korea (Samsung, SK Hynix) and increasingly caught up in the same [[Chip Export Controls]] and [[Supply Chain]] tensions as logic chips. Otherwise, RAM is infrastructure other entries point at, not a battlefield. ## See Also - [[Solid-State Drive]] — the permanent storage RAM is often confused with - [[Central Processing Unit]] — what RAM feeds - [[Semiconductor]] — the chip family memory belongs to
