Address Range:

$0300 - $3FFF

In NerdConsole, the first 16KB of RAM is called Main RAM. It represents a region of RAM that is almost always available. Due to the nature of the 65C02 CPU the Zero Page and Stack Page must always be located in the same place. Banking this region of RAM would require complex hardware to constantly keep those pages up to date in all banked regions so the decision was made to not support any banking in this region.

This region can be redirected to the PPU using the Main RAM Select register in the Control Page.

Return to Memory Regions.
