INFORMATION PROCESSING APPARATUS INCLUDING SRAM CAPABLE OF SHIFTING TO PLURALITY OF POWER SAVING MODES ACCORDING TO CONTROL SIGNAL AND CONTROL METHOD THEREOF

摘要

There is provided a control apparatus for controlling a static random access memory (SRAM) capable of shifting from a first power mode to a second power mode that is capable of holding data and saving more power than the first power mode or a third power mode that is not capable of holding data but is capable of saving more power than the second power mode. The control apparatus includes a first instruction unit configured to output an instruction for shifting the SRAM to the second power mode based on a state of the control apparatus and a second instruction unit configured to output an instruction for shifting the SRAM to the third power mode based on a state of the control apparatus.
