We present a detailed treatment of Crossbar Switching Networks (R-CSNs) made of resistive elements for memory utilization (as look-up table) in a nano FPGA. Initially, a technology assessment of this technology compared with a VLSI CMOS based memory is pursued considering area and support circuitry. Then, a graph mode is utilized for characterizing the effects of a single fault on the fault tolerant capabilities of a R-CSN. This is used to establish the exact analytical expression for the fault tolerance of a R-CSN in the presence of a single stuck-open/closed fault. The presented analysis confirms that small-sized R-CSNs are well suited as LUTs for FPGAs at nano scales.

Abstract

We present a detailed treatment of Crossbar Switching Networks (R-CSNs) made of resistive elements for memory utilization (as look-up table) in a nano FPGA. Initially, a technology assessment of this technology compared with a VLSI CMOS based memory is pursued considering area and support circuitry. Then, a graph mode is utilized for characterizing the effects of a single fault on the fault tolerant capabilities of a R-CSN. This is used to establish the exact analytical expression for the fault tolerance of a R-CSN in the presence of a single stuck-open/closed fault. The presented analysis confirms that small-sized R-CSNs are well suited as LUTs for FPGAs at nano scales.
