Abstract: The implementation of the present disclosure provides a memory, an operation method thereof and a memory system. For example, the memory can include a first memory plane, a second memory plane, and a plane data bus connected to each of the first memory plane and the second memory plane. The plane data bus can be configured to receive input data. The first memory plane can be configured to store first data of the input data. The second memory plane can be configured to store second data of the input data. The second data can be configured to indicate whether the first data has been performed with an inversion operation prior to transmission.
