Abstract
A circuit with a logical function of a computing-in-memory (CiM) operation, a memory device and a method thereof are provided. The circuit includes a first switch controlled by a first input data, a second switch controlled by an inverted first input data, a first and a second SOT MRAM cells, and a third switch controlled by a write word line. The first and the second SOT MRAM cells have a first and a second current paths for setting states of the first and the second SOT MRAM cells. In response to the third switch is turned-on, the state of the first SOT MRAM cell is different from the state of the second SOT MRAM cell. One of the state of the first SOT MRAM cell and the state of the second SOT MRAM cell is read according to one of the inverted first input data and the first input data.
