Description

technical field [0001] The invention relates to the field of circuits, in particular to a ferroelectric memory array capable of realizing multi-operand memory calculation. Background technique [0002] The calculation mechanism of the current storage-computing architecture only considers the calculation of two operands within one clock cycle. This also means that when a command needs to be executed on N rows, it takes N-1 clock cycles to operate. In addition, the existing integrated memory-computing architecture implements bit-wise logic operations mainly by sensing the resulting current / voltage of the bit line and comparing it with the reference current / voltage. But multiple operands require more reference currents or voltages, which will also bring high design costs. Therefore, how to effectively control the number of references when performing multiple operands is an inevitable problem. Contents of the invention [0003] In order to solve the above technical problems...
