Abstract
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.
