Abstract

The invention discloses a device with a data retention mode and a data processing mode, and the device includes a trigger and a control circuit. The flip-flop includes a flip-flop data input terminal and a flip-flop clock input terminal. The control circuit includes a control circuit data input terminal and a control circuit clock input terminal. The control circuit is configured to route an incoming data signal from the control circuit data input terminal to the flip-flop data input terminal and an incoming clock signal from the control circuit clock input terminal to the flip-flop clock input terminal in a data processing mode of the device , and apply a first given fixed signal value to the flip-flop data input terminal independently of the incoming data signal value in the data retention mode of the device, and apply a second given fixed signal value to the flip-flop independently of the incoming clock signal value clock input terminal.

Description

technical field [0001] The present application relates to an apparatus comprising a flipflop and having a data retention mode and a data processing mode and a method for the apparatus. Background technique [0002] Flip-flop based registers are used in a variety of circuits for storing state. To reduce the current consumption of such circuits, such circuits may include data processing modes for which the circuits perform desired functions. Furthermore, such devices or circuits may include so-called data retention modes or sleep or standby modes that interrupt the data processing of the device. In data retention mode, generally only low quiescent leakage current should be allowed. In addition, it is necessary to ensure that the device (such as an IC integrated circuit) can continue data processing immediately after changing from the data retention mode to the data processing mode. In addition, for flip-flops used in such devices, the state stored in the flip-flop even Both...
