Patent ID: 8885401

Claim:
A monolithic three-dimensional integrated circuit, comprising: a three-dimensional memory array including a first layer of memory cells and a second layer of memory cells, the first layer of memory cells includes a first memory cell, the second layer of memory cells includes a second memory cell, the first memory cell is located above the second memory cell, the second memory cell is located above a substrate, the first memory cell and the second memory cell are formed above the substrate without any intervening substrates between the first memory cell and the second memory cell; and a controller in communication with the three-dimensional memory array, the controller causes a first set of memory operations to be performed on the three-dimensional memory array, a first set of biasing conditions is applied to the three-dimensional memory array during the first set of memory operations, the controller detects that a load current associated with a voltage regulator biasing the three-dimensional memory array during the first set of memory operations is greater than a threshold, the controller determines a second set of biasing conditions different from the first set of biasing conditions in response to detecting that the load current is greater than the threshold, the controller causes a second set of memory operations to be performed on the three-dimensional memory array, the second set of biasing conditions is applied to the three-dimensional memory array during the second set of memory operations.
