A memory circuit served as a part within droids. As stated by Anzellan droidsmiths located on Nevarro, along with Peli Motto and Jawas, IG memory circuits had become scarce and were no longer in production by 9 ABY. When the Mandalorian, specifically Din Djarin, inquired with the Anzellans about repairing IG-11, they advised him to acquire a replacement droid, emphasizing that IG-11's cognitive functions would be impossible without a memory circuit.
