    • An interfacing circuit for reducing current consumption includes a command decoder, an operation controller, and a transmission controller. The command decoder decodes input packet commands and generates corresponding commands. The operation controller generates first through N-th operation signals for performing operations corresponding to the commands in response to a clock signal. The transmission controller transmits the first through N-th operation signals as first through N-th control signals in response to the clock signal. The transmission controller comprises a reset signal generator which generates a reset signal for interrupting the transmission of the first control signal when multiple commands of the first through N-th commands are generated simultaneously, wherein the commands would otherwise incorrectly operate the circuit receiving the first through N-th control signals when the commands are generated simultaneously. In this manner, the interfacing circuit offers the advantage that excessive current does not flow to the memory device, in the event that multiple commands are transmitted simultaneously.
    • 用于降低电流消耗的接口电路包括命令解码器,操作控制器和传输控制器。 命令解码器解码输入数据包命令并生成相应的命令。 操作控制器产生用于响应于时钟信号执行与命令相对应的操作的第一至第N操作信号。 传输控制器响应于时钟信号将第一至第N操作信号作为第一至第N控制信号发送。 传输控制器包括一个复位信号发生器,当多个第一至第N个命令同时产生时,该信号发生器产生用于中断第一控制信号传输的复位信号,其中命令将不正确地操作接收第一至第 同时产生命令时的第N个控制信号。 以这种方式,在多个命令被同时发送的情况下,接口电路具有过剩电流不流向存储器件的优点。
