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.
