| 10. A method of transferring information between a control device and one or more memory devices, the method comprising:
resetting the one or more memory devices by the control device applying a high voltage reset level on a single line, the high
voltage reset level being greater than a maximum voltage threshold representing a high logic level;
asserting a command mode by the control device applying a transition between a low logic level and the high logic level on
the single line;
sending command information encoded as a sequence of group code fields each with an adjoining control data field from the
control device to the one or more memory devices over a single input-output data bus;
decoding the group code fields and each adjoining control data field in the one or more memory devices; and
assembling a control word using the group code fields to direct placement of each corresponding control data field into a
sequence of control groups within the control word in the one or more memory devices.
