Apparatus and method for a current limiting bleeder device shared by columns of different memory arrays

摘要

Apparatus and method for a current limiting bleeder device that is shared between columns of different memory arrays and limits a current load on a voltage supply to prevent failure of an otherwise repairable memory device. The memory device includes first and second memory arrays having memory cells arranged in rows and columns where each of the columns of the first and second memory arrays have a equilibration circuit to precharge the respective column. A bleeder device is coupled to a precharge voltage supply and further coupled to at least one equilibration circuit of a column in the first memory array and to at least one equilibration circuit of a column in the second memory array to limit the current drawn by the equilibration circuits from the precharge voltage supply.
