In this paper, the design considerations of 3D vertical RRAM architecture are presented from the device, circuit to system level. Due to the voltage drop and sneak path problem, the sub-array size of the 3D NAND is still limited as compared with that of the 3D NAND. To be cost-competitive with the 3D NAND, high on-state resistance, high I-V nonlinearity and low interconnect resistivity is required to enable Mb 3D RRAM sub-array. Although the 3D RRAM has disadvantage in array efficiency (consequently in cost per bit) than the 3D NAND, the 3D RRAM outperforms the 3D NAND in throughput performance at system-level.Read More
