Abstract: Embodiments of the circuits described include a method wherein at least one command signal is activated. The activation of the at least one command signal causes a request to a testing circuit of a memory array to enter a memory test mode. The requested memory test mode permits at least part of the memory array to be read. In response to activation of the at least one command signal, a test control circuit initiates an overwrite sequence to overwrite the data stored in the memory array. The test control circuit enables the memory test mode once the overwrite sequence has been completed.

Abstract: An analog video signal supply circuit includes a processing circuit that supplies first and second digital video signals. First and second digital-to-analog converters convert digital signals to analog signals. A control circuit controls operation in a first configuration where the first digital video signal is applied to an input of the first digital-to-analog converter and the second digital video signal to an input of the second digital-to-analog converter. The control circuit further controls operation in a second configuration where the first digital video signal is simultaneously applied to the inputs of the first and second digital-to-analog converters.

Abstract: The present disclosure relates to a voltage regulation circuit including a first transistor connected between an input of voltage to be regulated and an output of a regulated voltage. A first regulation loop controls the first transistor according to a difference between a reference voltage and a first feedback voltage derived from the regulated voltage. A second transistor is connected in series between the first transistor and the output. A second regulation loop controls the second transistor according to a difference between the reference voltage and a second feedback voltage derived from the regulated voltage. The second regulation loop is active in low and high power regulation modes. A switch circuit forces the first transistor into an on state in a low power regulation mode.

Abstract: A diode control device include a first terminal for receiving a first power supply voltage and a second terminal for receiving a second power supply voltage. A circuit of the diode control device applies a regulated voltage on the anode of the diode in response to a control voltage. The control voltage is equal to a preset voltage when a reference voltage is less than or equal to zero. Conversely, when the reference voltage is greater than zero, the control voltage is equal to the sum of the present voltage and a difference between cathode voltage of the diode and the reference voltage.
