    Abstract: Provided is a three-dimensional storage device using wafer-to-wafer bonding. A storage device includes a first chip including a first substrate and a peripheral circuit region including a first control logic circuit configured to control operation modes of the non-volatile memory device and a second chip including a second substrate and three-dimensional arrays of non-volatile memory cells. The second chip may be vertically stacked on the first chip so that a first surface of the first substrate faces a first surface of the second substrate, and a second control logic circuit is configured to control operation conditions of the non-volatile memory device and is arranged on a second surface of the second substrate, the second surface of the second substrate being opposite to the first surface of the second substrate of the second chip.

    Abstract: A three-dimensional (3D) storage device using wafer-to-wafer bonding is disclosed. In the storage device, a first chip including a peripheral circuit region including a first control logic circuit configured to control operation modes of a nonvolatile memory (NVM) device is wafer-bonded with a second chip including 3D arrays of NVM cells, and a memory controller includes a third chip including a control circuit region. The control circuit region of the third chip includes a second control logic circuit associated with operation conditions of the NVM device, and the second control logic circuit includes a serializer/deserializer (SERDES) interface configured to share random access memory (RAM) in the memory controller and transmit and receive data to and from the NVM device.

    Abstract: A method of operating a memory system that comprises a memory device including a plurality of memory blocks and a memory controller, includes detecting a first memory block having a degradation count greater than or equal to a first reference value by the memory controller. A first command for the first memory block is transmitted to the memory device by the memory controller. A first voltage is applied to all of a plurality of word lines connected to the first memory block and a second voltage to a bit line connected to the first memory block in response to the first command by the memory device. The first voltage is greater than a voltage applied to turn on memory cells connected to all of the plurality of word lines. The second voltage is greater than a voltage applied to the bit line during program, read or erase operations.
