    • A system including a controller and a memory chip. The controller includes first and second selection signal terminals supplying first and second selection signals, respectively, multiple first data terminals and multiple second data terminals. The memory chip includes a semiconductor substrate, third and fourth selection signal terminals provided on the semiconductor substrate and electrically coupled to the first and second selection signal terminals of the controller, respectively. Multiple third data terminals are provided on the semiconductor substrate and electrically coupled to the first data terminals of the controller, respectively. Multiple fourth data terminals are provided on the semiconductor substrate and electrically coupled to the second data terminals of the controller, respectively. The first and third data terminals communicate first data in response to the first selection signal. The second and fourth data terminals communicate second data in response to the second selection signal.

    • To include first and second data input/output terminals allocated to first and second memory circuit units, respectively, and an address terminal allocated in common to these memory circuit units. When a first chip selection signal is activated, the first memory circuit unit performs a read operation or a write operation via the first data input/output terminal based on an address signal regardless of an operation of the second memory circuit unit. When a second chip selection signal is activated, the second memory circuit unit performs a read operation or a write operation via the second data input/output terminal based on the address signal regardless of an operation of the first memory circuit unit. With this configuration, a wasteful data transfer can be prevented, and the effective data transfer rate can be increased.
    • 分别包括分配给第一和第二存储器电路单元的第一和第二数据输入/输出端子以及共同分配给这些存储器电路单元的地址端子。 当第一芯片选择信号被激活时,与第二存储器电路单元的操作无关地,第一存储器电路单元基于地址信号经由第一数据输入/输出端执行读操作或写操作。 当第二芯片选择信号被激活时,第二存储器电路单元基于地址信号执行经由第二数据输入/输出端子的读取操作或写入操作,而与第一存储器电路单元的操作无关。 利用这种配置,可以防止浪费的数据传送,并且可以提高有效的数据传送速率。
