Abstract
A memory transistor and a selection transistor of an image sensor are connected in series and between a bit line (B) and a reference line (R). A gate electrode of the selection transistor is connected to a word line (W), which extends crosswise in relation to the bit line (B). A diode of the image sensor is switched between a gate electrode (G) of the memory transistor and a first source/drain area (S/D) of the memory transistor, which is connected to the selection transistor in such a way is polarized towards the first source/drain area (S/D) of the memory transistor and in the reverse direction. A photodiode of the image sensor is switched between a voltage connection and either the gate electrode (G) of the memory transistor or the first source/drain area (S/D) of the memory transistor in such a way that it is polarized towards the voltage connection and in the reverse direction.
