1. A method of assigning an identifier (ID) for a memory device configured in a daisy chain cascade arrangement having a plurality of devices, the method comprising:

  • processing, at a first memory device in the daisy chain cascade arrangement, a command causing the first device to enter a mode for assigning an identifier;

    asynchronously asserting an input to input a first value to the first memory device independent of a clock signal;

    asynchronously producing a second value from the first value independent of a clock signal;

    asynchronously asserting an output to output the second value from the first memory device to a second memory device in the daisy chain cascade arrangement independent of a clock signal, the output being configured to output control signals outside of the mode for assigning an identifier, the control signals being distinct from the first and second values; and

    holding an ID established for the first memory device based on the first value.
