Abstract: Memory devices in which a memory cell includes a thin film select transistor and a capacitor (1TFT-1C). A 2D array of metal-insulator-metal capacitors may be fabricated over an array of the TFTs. Adjacent memory cells coupled to a same bitline may employ a continuous stripe of thin film semiconductor material.
