Summary:To increase the number of selectable chips without adding a signal line to a general purpose memory controller. A semiconductor storage device includes a memory controller, a plurality of memory chips, a selection unit which is connected to the memory controller and is connected with the plurality of memory chips to be able to select any one of the plurality of memory chips, and a switch unit which is connected to the memory controller and the selection unit. The memory controller and the selection unit are connected by a signal line for transmitting a first signal outputted from the memory controller and configured to select the memory chips. The memory controller and the switch unit are connected by a signal line for transmitting a second signal outputted from the memory controller and configured to select the memory chips.
