Abstract:
1. A semiconductor storage device comprising: a nonvolatile first memory; a memory controller electrically connected to the first memory, and comprising management data for the first memory; a switch connected to the first memory and the memory controller, a power supply terminal being connected to the first memory and the memory controller through the switch; a second memory configured to store the management data read from the memory controller; an interpreter configured to interpret an instruction from a host device; a switch controller configured to turn off the switch based on an instruction from the memory controller, and turn on the switch based on an interpretation result of the interpreter; and a third memory configured to store an address of the management data in the second memory, wherein the memory controller is configured to write the management data to the second memory, thereafter instruct the switch controller to turn off the switch and, when electrically connected to the power supply terminal, read the management data from the second memory based on the address in the third memory.
