Headroom management during parallel plane access in a multi-plane memory device

Abstract

A memory device includes a memory array comprising a plurality of planes and a plurality of independent plane driver circuits. The memory device further includes control logic to receive a request for one of the plurality of independent plane driver circuits to execute a high current event on a corresponding one of the plurality of planes in the memory device. The control logic is further to increment a counter tracking a number of high current events occurring in the memory device, and determine whether the number of high current events occurring in the memory device satisfies a threshold criterion. Responsive to determining that the number of high current events occurring in the memory device satisfies the threshold criterion, the control logic is to cause execution of the high current event to be delayed.
