ABSTRACT:
A microprocessor, including a synchronous type memory having several parts, includes a power saving feature that places at least some parts of the memory in a non-operating state when instructions not requiring access to the memory are executed. An enable signal is generated when access is not required and a signal supplying circuit supplies a synchronous signal when the enable signal is not generated and supplies a signal in a predetermined state to place at least some parts or all parts of the memory in the non-operating state to reduce power consumption.
