Abstract

According to an embodiment, a memory system includes a plurality of memory cells and a memory controller. The memory controller executes a read operation on the plurality of memory cells using one or more reference read voltages to acquire a histogram representing the number of memory cells with respect to a threshold voltage. The memory controller inputs the histogram to a trained neural network model including an output layer for outputting one or more actual read voltages to read data from the memory cells. The memory controller executes a read operation on the memory cells using the one or more actual read voltages output from the output layer.
