Abstract:
An integrated circuit, comprising:an activation decoder having a number m command inputs for receiving digital commands of length m bits, wherein one of the digital commands is a deactivation command, an activation input for receiving an activation signal, and m outputs; a command decoder having a plurality of decoder inputs connected to said outputs of said activation decoder; said activation decoder, when the activation signal is at a first logic level, outputting at said outputs the command received at said command inputs; said activation decoder, when the activation signal is at a second logic level, outputting the deactivation command at said outputs irrespective of the command present at said command inputs; said command decoder having outputs, none of which are activated when the deactivation command is present at said decoder inputs, and one of which is in each case activated by said decoder when a command is present at said decoder inputs different from the deactivation command.
