  • Memory cell, memory array, method of forming and operating memory cell
    Patent number: 10923648
    Abstract: Various embodiments may relate to a memory cell. The memory cell may include a first cell electrode, a first insulator layer and a first magnetic free layer between the first cell electrode and the first insulator layer. The memory cell may also include a second cell electrode, a second insulator layer, and a second magnetic free layer between the second cell electrode and the second insulator layer. A magnetic pinned layer may be between the first insulator layer and the second insulator layer. A direction of magnetization of the first magnetic free layer may be changeable in response to a current flowing between a first end and a second end of the first cell electrode. A direction of magnetization of the second magnetic free layer may be changeable in response to a current flowing between a first end and a second end of the second cell electrode.
