New Brain-type Device with Human-like Memorizing and Forgetting Behavior
-A Single Artificial Device Realizes Complex Biological Synaptic Behavior-

Figure 1. Memorization model of the human brain. Rehearsal with the higher repetition rate causes the long-term memory (red line), and that with lower repetition rate only causes the short-term memory (blue line)

Figure 2. Experimental result of image storing using different repetition rates. ‘2’, which was inputted with the lower repetition rate, was stored in the short-term memory, resulting in the decay of the memorization level after the inputs. On the other hand, ‘1’, which was inputted with the higher repetition rate, was stored in the long-term memory maintained persistently.
