Abstract
A semiconductor storage device includes: a plurality of first memory arrays each including a plurality of semiconductor storage elements, in which data from an external device is written, and from which the data is read out to the external device, a second memory array which operates separately from the plurality of first memory arrays and which includes at least one block including a plurality of non-volatile semiconductor storage elements; and a data transfer section for transferring the data between the plurality of first memory arrays and the second memory array.
