Communication of power parameters between a power management integrated circuit and a memory system

A non-transitory computer-readable medium storing code comprising instructions which, when executed by processing circuitry of a memory system, cause the memory system to:

• monitor one or more parameters while operating the memory system in accordance with a first voltage and a first current supplied to the memory system by a power management circuit, wherein the one or more parameters are indicative of a power mode of the memory system;
• output, to the power management circuit via a first channel and in response to the one or more parameters satisfying one or more threshold values, a request that indicates a second voltage, a second current, or both associated with the power mode, wherein the first channel is different than a second channel for communication of data from the memory system to a host system;
• and
• operate in the power mode using the second voltage, the second current, or both supplied to the memory system by the power management circuit in response to outputting the request.

A method for memory operations at a memory system, comprising:

• monitoring one or more parameters while operating the memory system in accordance with a first voltage and a first current supplied to the memory system by a power management circuit, wherein the one or more parameters are indicative of a power mode of the memory system;
• outputting, to the power management circuit via a first channel and in response to the one or more parameters satisfying one or more threshold values, a request that indicates a second voltage, a second current, or both associated with the power mode, wherein the first channel is different than a second channel for communication of data from the memory system to a host system;
• and
• operating in the power mode using the second voltage, the second current, or both supplied to the memory system by the power management circuit in response to outputting the request.
