According to one aspect of the present disclosure, a memory system is provided. The memory system may include at least one memory. The at least one memory may include a memory array coupled to n wordlines. The n wordlines may be sequentially arranged by physical wordline identifiers, where n≥2. The memory system may include a memory controller coupled to the at least one memory. The memory controller may obtain multiple pieces of data to be written into the memory array. The memory controller may map n physical wordline identifiers to n virtual wordline identifiers. The physical wordline identifiers may respectively correspond to m adjacent virtual wordline identifiers spaced apart from each other, where 2≤m ≤n. The memory controller may generate check data based on data corresponding to the m adjacent virtual wordline identifiers. The check data may check and recover the data corresponding to the m adjacent virtual wordline identifiers.
