Claim 1:
2. A method of forming a microelectronic device, comprising:
forming a microelectronic device structure comprising memory cells, digit lines, word lines, and at least one isolation material covering and surrounding the memory cells, the digit lines, and the word lines, forming the microelectronic device structure comprising:
forming the digit lines, the word lines, and access devices of the memory cells at least partially within a base semiconductor structure of the microelectronic device structure, the digit lines and the word lines in electrical communication with the access devices;
forming conductive contact structures over and in electrical communication with portions of the word lines within word line exit regions horizontally neighboring the access devices;
forming storage node devices of the memory cells over and in electrical communication with the access devices of the memory cells; and
forming conductive redistribution layer (RDL) structures between and in electrical communication with the access devices and the storage node devices, each of the memory cells individually comprising one of the access devices, one of the storage node devices at least partially horizontally offset from the one of the access devices, and one of the RDL structures extending between and coupling the one of the access devices and the one of the storage node devices;

forming an additional microelectronic device structure comprising control logic devices and at least one additional isolation material covering and surrounding the control logic devices;
attaching the additional microelectronic device structure to the microelectronic device structure to form an assembly, the control logic devices overlying the memory cells within the assembly; and
forming contact structures extending through the at least one isolation material and the at least one additional isolation material after forming the assembly, some of the contact structures coupled to some of the digit lines and some of the control logic devices, and some other of the contact structures coupled to some of the word lines and some other of the control logic devices.
