SYSTEMS, METHODS, AND APPARATUS FOR FREQUENCY RESET OF A MEMORY
Abstract:
Some aspects of the disclosure include a self-refresh entry sequence for a memory, such as a DRAM, that may be used to avoid a frequency mismatch between a system processor and a system memory. The self-refresh entry sequence may signal the memory to reset the frequency set point state and default to the power-up state upon a self-refresh process exit. In another aspect, a new mode register may be used to indicate that the frequency set point needs to be reset after the next self-refresh entry command. In this aspect, the processor will execute a mode register write command followed by a self-refresh entry in response to the occurrence of a crash event. Then, the memory will reset to the default frequency set point by the end of self-refresh entry execution.
