Abstract: An integrated circuit device includes an array of RRAM cells, an array of bit lines for the array of RRAM cells, and an array of source lines for the array of RRAM cells. Both the source lines and the bit lines are in metal interconnect layers above the RRAM cells. The source line are thereby provided with a higher than conventional wire size, which increases the reset speed by approximately one order of magnitude. The lifetime of the RRAM transistors and the durability of the RRAM device are consequentially improved to a similar degree.
