Abstract
According to an embodiment, a semiconductor storage device includes a first storage unit, a read control unit, a second storage unit, and a write control unit. The first storage unit is configured to store data supplied from a host device. The read control unit is configured to perform control of reading the data in accordance with a read request. The second storage unit is configured to store a logical address used for reading the data from the first storage unit by the read control unit. The write control unit is configured to perform control of adding the stored logical address to the data and write the resulting data into the first storage unit in a case where a size of the data requested to be written into the first storage unit by the host device is smaller than a threshold.
