A unified address space doesn't always imply that the memory can be accessed from anywhere (although that might also be supported with some memory allocation mechanisms), and you still may have to copy between host and device memory. But it makes it much easier to have pointers in your GPU kernels, instead of having to deal with objects like OpenCL buffers.
