Abstract
A memory device, including: memory cells, first conductive lines, second conductive lines, third conductive lines and fourth conductive lines. The memory cells are arranged in an array. Each memory cell includes a transistor and a capacitor connected to a gate terminal of the transistor in series. The first conductive lines extend in a first direction. Each first conductive line connects to gate terminals of transistors arranged in same column in the array. The second conductive lines extend in the first direction. Each second conductive line connects to source terminals of transistors arranged in same column in the array. The third conductive lines extend in the first direction. Each third conductive line connects to drain terminals of transistors arranged in same column in the array. The fourth conductive lines extend in a second direction. Each fourth conductive line couples to the capacitor arranged in same row in the array.
