Figure 5

Schematic of various read current directions and their corresponding truth table. (a) Optical image of the read current direction (+x, +x) and its corresponding truth table. The logic gate is AND or NAND. (b) Optical image of the read current direction (−x, −x), identifying logic gate NOR or OR. (c) Optical image of the read current direction (−x, +x), reflecting logic gate Converse INH or Converse IMP. (d) Optical image of the read current direction (+x, −x), representing logic gate the INH or IMP. The red and blue arrows indicate that the read currents flowed toward the positive and negative x-axis at the same time, respectively. The all-logic gates are determined by selecting a non-inverting or inverting comparator.
