The number of selectable chips is increased without adding signal lines to a general-purpose memory controller. A semiconductor storage device is provided with: a memory controller; a plurality of memory chips; a selection unit connected with the memory controller and connected with the plurality of memory chips in such a manner that any of the plurality of memory chips can be selected; and a switch unit connected with the memory controller and the selection unit. The memory controller and the selection unit are connected through a signal line for transmitting a first signal output from the memory controller for selecting the memory chip. The memory controller and the switch unit are connected through a signal line for transmitting a second signal output from the memory controller for selecting the memory chip. 本发明提供种半导体存储装置，其无需对通用存储控制器追加信号线就能够增加可选择的芯片数。半导体存储装置包括：存储控制器；多个存储器芯片；选择部，其与上述存储控制器连接，并且能够选择上述多个存储器芯片中的任意者来与上述多个存储器芯片连接；和切换部，其与上述存储控制器和上述选择部连接。上述存储控制器与上述选择部通过传输从上述存储控制器输出的用于选择上述存储器芯片的第信号的信号线连接。上述存储控制器与上述切
