Abstract
Methods, systems, and devices for current budget adaption are described. A controller may be coupled with a set of memory devices. The controller may receive current consumption information from the set of memory devices and update a current consumption budget for the set of memory devices based on the current consumption information.
Claims23
An apparatus, comprising:
- a power supply line coupled with a set of memory devices;
- and
- a controller coupled with the set of memory devices and the power supply line, the controller configured to cause the apparatus to:
- determine whether a voltage of the power supply line is below a threshold;
- determine, in response to determining that the voltage is below the threshold, whether a collective amount of current consumed by the set of memory devices is within a range of an upper limit for current consumption by the set of memory devices;
- and
- update the upper limit for consumption of current by the set of memory devices based at least in part on determining that the collective amount of current is within the range.

An apparatus, comprising:
- a power supply line coupled with a set of memory devices;
- and
- a controller coupled with the set of memory devices and the power supply line, the controller configured to cause the apparatus to:
- receive a set of one or more messages each indicating a respective amount of consumption of current for each memory device of the set of memory devices;
- determine, based at least in part on the set of one or more messages, a correlation between a collective amount of consumption of current by the set of memory devices and a corresponding decrease in a voltage on the power supply line;
- and
- update an upper limit for consumption of current by the set of memory devices based at least in part on the correlation.
4 more elements
An apparatus, comprising:
- a memory device;
- a power supply line coupled with the memory device;
- and
- a local controller coupled with the memory device and configured to cause the apparatus to:
- determine a respective amount of current consumption associated with the memory device;
- communicate an indication of the respective amount of current consumption to a controller coupled with the memory device;
- and
- receive, based at least in part on communicating the indication, a control signal indicating an updated upper limit for a consumption of current for the memory device.
