# Memory
- Addresses are 64 bit
- Program should be in the same address space as all other data
- Address `0x0` is invalid and acessing it traps
- Memory implementation is arbitrary
- In case of accessing invalid address:
- Program shall trap (LoadAccessEx, StoreAccessEx) with parameter of accessed address
- Value of register when trapped is undefined
## Recommendations
- Leave address `0x0` as invalid
- If paging used:
- Leave first page invalid
- Pages should be at least 4 KiB
