摘要: A memory device and a memory data determination method are provided. The memory device may estimate a threshold voltage shift of a first memory cell based on data before the first memory cell is programmed and a target program threshold voltage of the first memory cell. The memory device may generate a metric of a threshold voltage shift of a second memory cell based on the estimated threshold voltage shift of the first memory cell. Also, the memory device may determine data stored in the second memory cell based on the metric.
