Patent Primary Examiner
A storage device and a manufacturing method thereof are provided. The storage device includes a first chip and a second chip. The second chip is stacked on the first chip in a third direction. The first chip includes a storage array, and the storage array includes at least one storage block. An occupied area after the first chip and the second chip are stacked can be reduced by constructing a first local bit line decoder block, a second local bit line decoder block, a first word line decoder block, and a second local bit line decoder block in a top view projection area, thereby reducing plane occupied space of the storage device. This is beneficial for minimizing the size of the storage device.
