Solid-state drive has the gates which are not electrically connected and writes information by push electrons into the gates using tunnel effect. How does the human brain work?

• (3.2.1) Synapse transmitting a signal
• (3.2.2) Long-term potentiation of synapses
• (3.2.3) Gradually make the memory solid
