Abstract
Methods of operating a die might include determining an expected peak current magnitude of the die for a period of time, and outputting the expected peak current magnitude from the die prior to completion of the period of time. Apparatus might be configured to perform similar methods.
Claims30
A method, comprising:
- determining whether a die is expected to make a transition during a period of time, wherein the transition is selected from a group consisting of initiating a next phase of an operation being performed by the die and initiating a first phase of a next operation to be performed by the die;
- determining an expected peak current magnitude of the die for the period of time after determining whether the die is expected to make the transition during the period of time;
- and
- outputting the expected peak current magnitude from the die prior to completion of the period of time.

A method of operating a plurality of dies, comprising:
- for each value of N from Ninit to D in a sequence, wherein N, Ninit and D are integers, and wherein (D−Ninit+1) equals a number of dies of the plurality of dies:
- determining whether the Nth die is expected to make a transition during a corresponding period of time, wherein the transition of the Nth die is selected from a group consisting of initiating a next phase of an operation being performed by the Nth die and initiating a first phase of a next operation to be performed by the Nth die;
- determining an expected peak current magnitude of the Nth die for its corresponding period of time after determining whether the Nth die is expected to make the transition of the Nth die during its corresponding period of time;
- and
- broadcasting the expected peak current magnitude from the Nth die prior to completion of its corresponding period of time.
