Abstract
A method and apparatus for assigning identification values to memories. A master resets identifiers of a first memory and a second memory by sending a reset signal on a line that is coupled in a daisy-chained manner to the first and second memories and also coupled to the master. The master places a first identification value on a data bus coupled to the master and to the first and second memories. The first memory stores the first identification value on the data bus as an identifier for the first memory when the master sends a first storage signal to the first memory via the daisy-chained line. The master places a second identification value on the data bus. The second memory stores the second identification value on the data bus as an identifier for the second memory when the master sends a second storage signal to the second memory via the daisy-chained line.
