Abstract:
1. A non-volatile storage system, comprising: a memory array, the memory array includes a plurality of rewriteable non-volatile memory cells, each memory cell of the plurality of rewriteable non-volatile memory cells includes a reversible resistance-switching element without an isolation element in series with the reversible resistance-switching element, the plurality of rewriteable non-volatile memory cells includes a first group of memory cells connected to a first word line comb and a second group of memory cells connected to the first word line comb, the first word line comb includes a plurality of fingers, the first group of memory cells includes a plurality of far cells, each memory cell of the plurality of far cells is located at a far end of one of the plurality of fingers, the second group of memory cells includes a plurality of near cells, each memory cell of the plurality of near cells is located at a near end of one of the plurality of fingers, the first group of memory cells comprises a first number of memory cells and the second group of memory cells comprises a second number of memory cells greater than the first number of memory cells; and one or more managing circuits in communication with the memory array, the one or more managing circuits cause a first forming operation to be performed to the first group of memory cells, the one or more managing circuits cause a second forming operation to be performed to the second group of memory cells subsequent to the first forming operation.
