Abstract
Systems, methods, circuits, and apparatus including computer-readable mediums for protecting memory cells from in-process charging effects for a memory system, e.g., NAND flash memory. The methods include: forming a first connection to connect a first node of a diode to a memory cell line coupled with one or more memory cells to be fabricated and a second connection to connect a second node of the diode to a control circuit, such that, during fabricating the memory, in-process charges accumulated on the memory cells are discharged to a ground via a conductive path formed by a first voltage caused by the in-process charges forward biasing the diode and then enabling the control circuit to conduct a current to the ground, and after fabricating the memory and during operating the memory, turning off the conductive path by reverse biasing the diode with a second voltage applied on the control circuit.
