Memory
The Alpha has a 64-bit linear virtual address space with no memory segmentation. Implementations can implement a smaller virtual address space with a minimum size of 43 bits. Although the unused bits were not implemented in hardware such as TLBs, the architecture required implementations to check if they are zero to ensure software compatibility with implementations that implemented a larger or the full virtual address space.

Famous quotes containing the word memory:
“Then, lastly, let some weekly strewings be
Devoted to the memory of me:
Then shall my ghost not walk about, but keep
Still in the cool and silent shades of sleep.”
