How much memory does a sidewalk really need?

A moving sidewalk is a lot like a computer. It needs to have a binary code to let it know when to turn on. It can't be moving forever, that would just be a gross waste of energy. Also, it needs a certain amount of memory in it. In order to operate smoothly, you probably need 1 TB of data, the equivalent of 1,000,000 minutes of music. This so that we avoid any complications with the sidewalk, and controlling the speed and such. Other than that, it doesn't really seem like running a moving sidewalk is such a complicated process. A 0 in the binary code means that it should stop,  a 1 means go. We could conceivably alternate speeds during the day, which would make the process more complicated, however, its probably better to have one standard speed so as not to discriminate against anyone who has time crunches at various points in the day. Therefore, the actually operation process would not take that much energy/memory. Its likely that 1 TB is probably overkill.
