Abstract
A three-dimensional (3D) memory device includes a first stack structure, a first channel structure, a second stack structure, and a second channel structure. The first stack structure includes interleaved first conductive layers and first dielectric layers. The first channel structure extends through the first stack structure along a first direction. The first channel structure includes a first semiconductor channel, and a first memory film over the first semiconductor channel. The first memory film includes a storage layer. The storage layer is separated by the first dielectric layers into a plurality of sections.
