Abstract:
An information handling system includes a memory device having a voltage regulator enabled by a command from a processor. The memory device provides an indication to a logic device that the voltage regulator successfully powered up the memory device. A failure to provide the indication within a time duration indicates that the voltage regulator failed to successfully power up the memory device. The logic device determines that the processor issued the first command, sends a second indication to the processor indicating that the first voltage regulator successfully powered up the first memory device when the first indication is received within the first time duration after determining that the processor issued the first command, and sends a third indication to the processor that the first voltage regulator failed to successfully power up the first memory device when the first indication is not received within the first time duration after determining that the processor issued the first command.
