    摘要: A neuromorphic device includes a synapse. The synapse includes a first electrode, a second electrode spaced apart from the first electrode, an oxygen-containing layer disposed between the first electrode and the second electrode, a reactive metal layer disposed between the oxygen-containing layer and the second electrode, and an oxygen diffusion-retarding layer disposed between the reactive metal layer and the oxygen-containing layer. The oxygen-containing layer includes a P-type material and oxygen ions. The reactive metal layer reacts with the oxygen ions of the oxygen-containing layer. The oxygen diffusion-retarding layer includes an N-type material and interferes with a movement of the oxygen ions from the oxygen-containing layer to the reactive metal layer. An interface between the oxygen-containing layer and the oxygen diffusion-retarding layer is a P-N junction.

    摘要: A semiconductor device includes a controller configured to control a first memory device to process a request for the first memory device and a second memory device. The controller receives the request for the first memory device, determines a data damage risk of cells connected to a second signal line adjacent to a first signal line of the first memory device corresponding to a requested address by referring to information indicating a data damage risk, and stores data of the cells connected to the second signal line in the second memory device when determining that there is a data damage risk.

    摘要: A method reads data from a synapse which includes a transistor and a variable resistor. The transistor has a gate electrode, a first electrode and a second electrode. The variable resistor has a first electrode connected to the second electrode of the transistor. The method includes applying a read voltage to the gate electrode of the transistor, applying a pre-synaptic voltage to the first electrode of the transistor, and applying a post-synaptic voltage to a second electrode of the variable resistor. The read voltage is lower than the threshold voltage of the transistor.
