Abstract
Power consumption while in a low power suspend mode is enhanced by placing a portion of suspend and resume instructions into internal rewriteable memory, such as internal random access memory (“IRAM”). During entry into suspend, control is transferred from instructions stored in an external memory to instructions stored within the internal rewriteable memory. These instructions are configured to reduce power consumption of the external memory by reducing a slew rate, drive strength, and so forth. Upon awakening from suspend, the instructions within the internal rewriteable memory place the external memory back to an operational state and control passes back to the instructions stored within external memory.
