Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/079575
Kind Code:
A1
Abstract:
Provided is a semiconductor device having a novel configuration. This semiconductor device has: a first element layer having a bit line drive circuit; a second element layer having a first switch circuit, a first memory cell, and first wiring provided between the first switch circuit and the first memory cell; and a third element layer having a second switch circuit, a second memory cell, and second wiring provided between the second switch circuit and the second memory cell. The first switch circuit has a function for bringing the first wiring and third wiring into a non-conducting state during a data write operation or read operation of the second memory cell. The second switch circuit has a function for bringing the second wiring and the third wiring into a non-conducting state in a data write operation state or a data read operation state of the first memory cell.
