Title:
SYMMETRICAL TYPE MEMORY CELL AND BNN CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/040853
Kind Code:
A1
Abstract:
The present disclosure provides a symmetrical type memory cell and a BNN circuit. The symmetrical type memory cell comprises a first complementary structure and a second complementary structure; the second complementary structure is symmetrically connected to the first complementary structure in a first direction; the first complementary structure comprises a first control transistor used for being connected to the second complementary structure; the second complementary structure comprises a second control transistor; the drain electrode of the second control transistor and the drain electrode of the first control transistor are symmetrically arranged in the first direction, and are simultaneously connected to a bit line; and the symmetrical type memory cell is used for storing the weight value 1 or 0. By means of the symmetrical type memory cell of the present disclosure, the breakpoint data of the BNN circuit can be kept, power consumption is reduced, the area of a memory is greatly reduced, time delay is reduced, and the BNN circuit can realize a large-scale parallel reasoning operation.
