Abstract:
A semiconductor storage device has a nonvolatile semiconductor memory comprised from multiple storage areas, and a controller, which is coupled to the nonvolatile semiconductor memory. The controller (A) identifies a storage area state, which is the state of a storage area, (B) decides, based on the storage area state identified in the (A), a read parameter, which is a parameter for use when reading data from a storage area with respect to a storage area of this storage area state, and (C) uses the read parameter decided in the (B) with respect to a read-target storage area and reads data from this read-target storage area.

Claim (Index 1):
A semiconductor storage device, comprising:\n a nonvolatile semiconductor memory comprising a plurality of storage areas; and a controller which is coupled to the nonvolatile semiconductor memory; wherein the controller is configured to manage degree of deterioration for each of storage areas, the degree of deterioration is based on the number of error bits of data which is written in a storage area of the plurality of storage areas; wherein the controller is configured to manage read parameter information including one or more read parameters relevant to the degree of deterioration; wherein the controller is configured to specify a first read parameter corresponding to a first storage area of the plurality of storage areas, based on the degree of deterioration corresponding to the first storage area and the read parameter information; and wherein the controller is configured to read data from the first storage area by using the first read parameter.
