ABSTRACT:
A method for the resetting of a group of series-connected non-transparent synchronous memory cells. The method includes modifying the clock signals that control the transfer gates of these cells on the activation of a resetting signal to set all the transfer gates in the on state. The method is particularly suited to the resetting of long shift registers such as those used in cryptographic applications, especially in micro-circuit cards, and the reset circuitry can be implemented using conventional logic gates.
