    • An address identifying memory block is match-compared with address information stored in a to-be-remedied block memory section in a block redundancy judge section. A redundant block select signal is outputted from the block redundancy judge section by judgment of address match. A memory block column select section selects a memory block column having a redundant memory block irrespective of an address signal as the redundant block select signal is activated if block redundancy is activated to output a memory block column select signal. A column redundancy memory section selects address information of column redundancy relating a redundant memory block arranged in a memory block column in accordance with the memory block column select signal.
    • 地址识别存储器块与块冗余判断部分中存储在待修复块存储器部分中的地址信息进行匹配比较。 通过地址匹配的判断从块冗余判断部分输出冗余块选择信号。 如果块冗余被激活以输出存储块列选择信号,则存储块列选择部分选择具有冗余存储块而不管地址信号的存储块列,因为冗余块选择信号被激活。 列冗余存储器部分根据存储器块列选择信号选择与排列在存储器块列中的冗余存储器块有关的列冗余的地址信息。

    • In inputting control information for setting access conditions in a system having a common data bus (3), when a predetermined bit string making up an access condition setting command is inputted to predetermined terminals which are not data input/output terminals (S3), the predetermined terminals are set as control information input terminals (S5) and inputted control information is temporarily maintained in a non-volatile memory device (S13). When inputting of control information is completed (S15), the control information that has been temporarily maintained is stored in a non-volatile memory region all at once (S17). During an access condition setting operation, the data input/output terminals are released (S7) and the data bus (3) is made available to other banks or devices (2) so that data transfer efficiency of the system can be improved.
    • 在输入具有公用数据总线(3)的系统中设定存取条件的控制信息时,当构成存取条件设定指令的规定位串被输入到不是数据输入输出端子的规定端子(S 3)时, 将预定端子设置为控制信息输入端子(S 5),并将输入的控制信息暂时保持在非易失性存储器件中(S13)。 当完成控制信息的输入(S15)时,暂时保持的控制信息一次存储在非易失性存储区域(S17)。 在访问条件设置操作期间,释放数据输入/输出端子(S7),使数据总线(3)可用于其他存储体或设备(2),从而可以提高系统的数据传输效率。
