Abstract

According to various embodiments, a memory cell may include: a field-effect transistor structure comprising a channel region and a gate structure disposed at the channel region, the gate structure comprising a gate electrode structure and a gate isolation structure disposed between the gate electrode structure and the channel region; and a memory structure comprising a first electrode structure, a second electrode structure, and at least one remanent-polarizable layer disposed between the first electrode structure and the second electrode structure; wherein the first electrode structure of the memory structure is electrically conductively connected to the gate electrode structure of the field-effect transistor structure.
