Abstract
A memory structure including a substrate and memory cells is provided. The memory cells are stacked on the substrate. Each memory cell includes a first conductive layer, a first gate, a second gate, a second conductive layer, a channel layer, and a first charge storage layer. The first conductive layer, the first gate, the second gate, and the second conductive layer are sequentially stacked. The first conductive layer and the first gate are electrically insulated from each other. The first gate and the second gate are electrically insulated from each other. The second gate and the second conductive layer are electrically insulated from each other. The first gate and the second gate are electrically insulated from the channel layer. The first conductive layer and the second conductive layer are electrically connected to the channel layer. The first charge storage layer is located between the first gate and the channel layer.
