摘要： According to one embodiment, a memory system comprises a non-volatile semiconductor memory, a memory and a controller. The memory stores a management table including a plurality of parameters for managing the non-volatile semiconductor memory. The controller is configured to control the operation of the non-volatile semiconductor memory based on a first value of the parameters contained in the management table. The controller obtains a second value corresponding to the parameters from an operation log of the non-volatile semiconductor memory, compares the second value of the parameters with the first value, calculates the difference between the second value of the parameters and the first value when they are different from each other, calculates a correction value for correcting the first value when the difference is greater than a third value, and updates the first value of the management table based on the correction value.
