    摘要: According to one embodiment, there is provided memory system including a non-volatile memory device, a monitoring unit, and a changing unit. The non-volatile memory device stores data. The monitoring unit monitors a characteristic of the non-volatile memory device when writing and erasing processes are performed to write and erase the data to and from the non-volatile memory device. The changing unit changes at least one of a value of a writing start voltage and an increase width of a writing voltage in the writing process in accordance with the monitored characteristic so that a time for the writing process is substantially identical to a target value. The writing process is a process in which a writing operation and a verification operation are alternately repeated.
