See also list of RAM areas by name.

The eZ80 has a 24-bit linear address space. Layout:

• 000000h: Start of flash. The first 128 K are locked boot sectors. The first 8 are divided into 8 K sectors, all of which are locked. Implies that there is no longer a certificate.
• 000066h: Flash exception handler. Write-to-flash without permission triggers the non-maskable interrupt to fire.
• 00007Eh: Hardware/Emu flag: This byte indicates whether the ROM is a hardware ROM or emulator.
• 000080h: Start of boot code jump table.
• D00000h: Start of RAM. 256 K.
• D40000h: Start of VRAM. 320x240x2 bytes = 153600 bytes.

Possible (Unconfirmed) safeRAM areas:

• D1787C: 8192 bytes
• D3FEFF: 255 bytes
