    • A semiconductor device has operation modes selectable through the control by a second microcomputer (113). In a first mode, an operation of a memory controller (105) responding to a memory card command from a memory card interface terminal and an operation of a first microcomputer (106) responding to an IC card command from an IC card interface terminal are separately performed. In a second mode, the first microcomputer operates in response to the IC card command from the IC card interface terminal. In a third mode, the memory controller and the first microcomputer operate in response to an undefined IC card command from the IC card interface terminal. In a fourth mode, the memory controller and the first microcomputer operate in response to the memory card command from the memory card interface terminal. Convenience of the semiconductor device having an IC card function and a memory card function is improved.
    • 半导体器件具有通过第二微型计算机(113)的控制可选择的操作模式。 在第一模式中,分别响应来自存储卡接口终端的存储卡命令的存储器控​​制器(105)的操作和来自IC卡接口终端的响应IC卡命令的第一微计算机(106)的操作 执行。 在第二模式中,第一微型计算机响应于来自IC卡接口终端的IC卡命令而工作。 在第三模式中,存储器控制器和第一微型计算机响应于来自IC卡接口终端的未定义的IC卡命令来操作。 在第四模式中,存储器控制器和第一微型计算机响应来自存储卡接口终端的存储卡命令而操作。 提高具有IC卡功能和存储卡功能的半导体器件的便利性。
