docs: Returns an array which identifies the memory layout. Each entry
      of the array will contain a dictionary with the following keys:
          addr        - Address of this memory segment
          last_addr   - Last address contained within the memory segment.
          size        - size of the segment, in bytes
          num_pages   - number of pages in the segment
          page_size   - size of each page, in bytes
