Abstract

The invention provides a semiconductor device and a preparation method thereof. The semiconductor device comprises a plurality of wafers which are bonded with each other, a plurality of storage arrays which are respectively arranged on the plurality of wafers, a plurality of drivers which are electrically connected with the plurality of storage arrays in a one-to-one correspondence manner, and a common controller which is arranged on one of the plurality of wafers, and the common controller is electrically connected with the plurality of drivers and used for controlling the plurality of drivers to process data of the plurality of storage arrays. The common controller in the semiconductor device can control the plurality of drivers to control the plurality of storage arrays to perform read-write operation, so when the semiconductor device needs to carry out operations such as memory change and the like, data communication can be carried out without the help of an external circuit and wiring, therefore, the data communication speed between different memory arrays in the semiconductor device is effectively improved, and meanwhile, the manufacturing cost of the semiconductor device is reduced.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a semiconductor device and a preparation method thereof. Background technique [0002] As technology develops, the semiconductor industry is constantly seeking new ways to produce a greater number of memory cells per memory die in a memory device. In order to further increase the storage density of the memory, a memory device with a three-dimensional structure has been developed. The three-dimensional memory includes multiple memory cells stacked along the vertical direction, which can double the integration level on a wafer per unit area and reduce the cost. Among non-volatile memories, 3D NAND Flash (three-dimensional NAND flash memory) memories with 32 layers, 64 layers, or even higher layers have been designed. [0003] In the prior art, a phase change memory (Phase Change Memory, PCM) is usually used as a buffer of the 3D NAND Flash memory to improve the speed and pe...
