Wuhan Xinxin Semiconductor Manufacturing Assigned Patent

Wuhan Xinxin Semiconductor Manufacturing Co., Ltd., Hubei, China, has been assigned a patent (11605640) developed by Jeong, Jongbae, Hubei, China, for “storage device and manufacturing method thereof.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “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.”

The patent application was filed on 2021-12-05 (17/542427).
