    Abstract: A nonvolatile memory device includes a memory array having multiple nonvolatile memory cells, a first read circuit and a second read circuit. The first read circuit is configured to read first data from the memory array during a first read operation and to provide one or more protection signals indicating a victim period during the first read operation. The second read circuit is configured to read second data from the memory array during a second read operation and to provide one or more check signals indicating an aggressor period during the second read operation.

    Abstract: A nonvolatile memory device comprises a memory core comprising a plurality of variable resistance memory cells, an input/output (I/O) circuit configured to receive a first packet signal and a second packet signal in sequence, the first and second packet signals collectively comprising information for a memory access operation, and further configured to initiate a core access operation upon decoding the first packet signal and to selectively continue or discontinue the core access operation upon decoding the second packet signal, and a read circuit configured to perform part of the core access operation in response to the first packet signal before the second packet signal is decoded.
