Abstract:
1. A memory system, comprising: a nonvolatile memory area; a first interface configured to be connected to a first host device; a second interface configured to be connected to a second host device through wireless communication; and a controller configured to control the first interface such that the first host device is configured to prohibit to write data into the nonvolatile memory area on a basis of a command provided from the second host device before the second host device writes data into the nonvolatile memory area through the second interface; wherein the first interface notices an error to the first host device when the first host device writes data into the nonvolatile memory area in a state that the first host device is prohibited to write data into the nonvolatile memory area, and the second host device transmits data from a portion of the nonvolatile memory area other than a portion of the nonvolatile memory area in which the second host device writes data into the nonvolatile memory area.
