Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/049013
Kind Code:
A1
Abstract:
Provided is a novel semiconductor device. The semiconductor device comprises a plurality of cell arrays and a plurality of peripheral circuits, wherein each cell array has a plurality of memory cells; each peripheral circuit has a first drive circuit, a second drive circuit, a first amplification circuit, a second amplification circuit, a third amplification circuit and a fourth amplification circuit; the first drive circuit and the second drive circuit have the function of supplying a selection signal to a cell array; the first amplification circuit and the second amplification circuit have the function of amplifying a potential inputted from a cell array; the third amplification circuit and the fourth amplification circuit have the function of amplifying a potential inputted from the first amplification circuit or the second amplification circuit; the first drive circuit, the second drive circuit, the first amplification circuit, the second amplification circuit, the third amplification circuit and the fourth amplification circuit each have a region overlapping a cell array; and the memory cells include a metal oxide in the channel formation region.
