devices, with memories of the external computer corresponding
to memories in the portable device, we think it is reasonable
to conclude that there is a “mapping” in Yokozawa between the
watch (i.e., the portable device) memory and the external
computer memory. It is also clear that the external computer
in Yokozawa manipulates its memory to modify information
therein during processing. Yokozawa then downloads the entire
program to the memory of the portable device. When the entire
program, including any updated information, is downloaded to
the portable device in Yokozawa, so too are any memory
modifications downloaded at that time, from the computer memory
to the watch memory. It is true that Yokozawa does not
download only the memory modifications, since even the
unmodified memory is downloaded, but claims 1, 3, 4 and 16 do
