RAM chips may be dynamic memory. They may also be static memory. I
have this nice 256k battery backed up static S-100 memory board in
storage. The difference is that you have to refresh dynamic RAM even
if it is powered up. You do not have to refresh static RAM as long
as you keep it powered up. But static RAM usually costs more.
