Abstract
Systems and methods for reducing peak power supply current in a non-volatile memory system that includes a plurality of memory die are described. In some cases, prior to a first memory die of the plurality of memory die performing a particular memory operation (e.g., a programming operation), the first memory die may poll other memory die of the plurality of memory die to determine a total peak power supply current for the plurality of memory die. In response to detecting that the total peak power supply current for the plurality of memory die is at or above a peak current threshold (e.g., more than 200 mA), the first memory die may delay the performance of the particular memory operation or slow down the performance of the particular memory operation.
