QUANTIZATION OF PEAK POWER FOR ALLOCATION TO MEMORY DICE

Abstract:

A method for managing power amongst a set of memory devices that are provided a peak power that is quantized into a set number of power tokens. The method includes determining that the first memory die is to change from a lower power state that requires a first number of tokens to a higher power state that requires a second number of tokens. The method further includes transmitting a message in response to determining that the sum of the second number and a third number of power tokens allocated to other memory devices in the set of memory devices satisfies a threshold number of power tokens. The message includes the second number and is transmitted on a bus that is shared by the set of memory devices.
