A method and system for the selective broadcasting of commands to a subset of a plurality of devices connected in series to a memory controller, where each of the plurality of devices has a unique identification number (ID). The memory controller designates the subset of devices to execute the command, excluding the non-selected devices from executing the command. The memory controller encodes the ID numbers of the designated devices into a single coded address, and sends the command along with the coded address in a packet to the series connected devices. Each device receives the packet in a serial bitstream and decodes the coded address using its ID number in order to determine whether it is selected or not. If the device is selected, the command is executed. Otherwise, the packet is forwarded without executing the command.
