From the Wiki:
So these are internal to the PPU, but have their own address space? Yet I see the palettes listed on the main VRAM memory map ($3F00-$3F1F) and not the OAM. What's the actual underlying physical arrangement? Both the Wiki and other documentation I've perused are unclear.

Two separate, smaller address spaces hold a palette, which controls which colors are associated to various indices, and OAM (Object Attribute Memory), which stores the position, orientation, shape, and color of the sprites, or independent moving objects. These are internal to the PPU itself and use dynamic memory (which will slowly decay if the PPU is not rendering data).
