    Abstract: A method to construct a 3D system, the method including: providing a base wafer; transferring a first memory wafer on top of the base wafer; thinning the first memory wafer, thus forming a thin first memory wafer; transferring a second memory wafer on top of the thin first memory wafer; thinning the second memory wafer, thus forming a thin second memory wafer; and transferring a memory control wafer on top of the thin second memory wafer; where the transferring a memory control wafer includes bonding of the memory control wafer to the thin second memory wafer, and where the bonding includes oxide to oxide and conductor to conductor bonding.
