    • A method of accessing electronic memory is provided in electronic circuits where it is desired to lower power consumption and hence there is no active oscillator at the time when access to data within the electronic memory is required. The invention provides a method therefore for accessing the electronic memory from a controller, which generates its own clock signals from a data, communications bus electrically coupled to the controller. Advantageously the method allows for memory access to be continued in integrated circuits where a subset of circuits are powered down to reduce power consumption, and one of the subset of circuits is an oscillator.
    • 在需要降低功耗的电子电路中提供了访问电子存储器的方法,因此在需要访问电子存储器内的数据时没有活动振荡器。 本发明提供了一种用于从控制器访问电子存储器的方法,控制器从控制器电连接的数据通信总线产生其自己的时钟信号。 有利地,该方法允许在集成电路中继续存储器访问,其中电路的子集被掉电以降低功耗,并且电路子集之一是振荡器。
