The Amiga's memory architecture is fundamentally different from any other home computer of its era. Rather than treating all RAM as equal, the system divides memory into **distinct classes** based on which hardware can access it. This division exists because the custom chipset (Agnus/Alice, Denise/Lisa, Paula) has its own DMA engine that operates on a dedicated bus — and that bus only reaches certain RAM.
|
||||
|
||||
Understanding this distinction is not optional. It determines where screen buffers live, why games run faster with expansion RAM, why the [Blitter](../../08_graphics/blitter_programming.md) can't touch Fast RAM, and why a $50 accelerator card with 8 MB of Fast RAM can feel like a new machine.

|

> The 68000 is **Big-Endian**. All multi-byte values in memory (pointers, word-sized registers, structure fields) are stored most-significant byte first. Modern developers working with Amiga memory dumps or binary formats will misread data if they assume little-endian layout.
