PROBLEM TO BE SOLVED: To provide a memory system capable of easily setting an extension function.SOLUTION: A memory system of an embodiment comprises: a nonvolatile semiconductor memory device; a control unit that controls the nonvolatile semiconductor memory device; an extension function unit that is controlled by the control unit; and an extension register that has a fixed block length in which an extension function of the extension function unit can be defined. The memory system also has a converter that includes a separation unit that separates the header data and variable-length command data of a command that is transferred from a host device; and a command issuing unit that generates a first command for writing to the extension function unit the command header data which has been separated by the separation unit, and generates a second command for reading out the header data of a response from the extension function unit via the extension register. |
