Abstract:
A semiconductor memory device includes a nonvolatile memory and a controller. The nonvolatile memory has a plurality of memory cells that are connected to word lines to which a read voltage is applied at the time of reading data stored in the memory cells. The controller is configured to determine a read voltage for a target memory cell by selecting a tracking parameter based on a word line connected to the target memory cell and an elapsed time from a previous access to a group of memory cells including the target memory cell, and executing a tracking process on the memory cells also connected to the word line connected to the target memory cell using the selected tracking parameter.

Claim (Index 6):
The semiconductor memory device according to  claim 1 , further comprising:\n first and second tables, each associating the word lines to a plurality of elapsed times, and a plurality of tracking parameters, wherein the controller selects one of the first and second tables based on an access count of the group of memory cells and selects, from the selected table, the tracking parameter associated with the word line connected to the target memory cell and the elapsed time.
