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 17):
A computing device, comprising:\n a host device; and a semiconductor memory device including a host interface configured to receive commands from the host device, a nonvolatile memory that has a plurality of memory cells, the plurality of memory cells being connected to word lines to which a read voltage is applied at the time of reading data stored in the memory cells, and a controller 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.
