Abstract
A memory system includes a nonvolatile memory including a memory cell, and a controller. The controller is configured to write multi-bit data into the memory cell through a first write operation of writing a first part, and not a second part, of the multi-bit data and then a second write operation of writing the first and second parts. The controller is configured to, during writing of the multi-bit data, determine an amount of time that has passed since the first write operation, perform the second write operation in a first manner by inputting the second part, and not the first part, from the controller, when the determined amount is less than a threshold amount, and perform the second write operation in a second manner by inputting the first and second parts from the controller, when the determined amount is greater than the threshold amount.
