Abstract :
A practical system for reading out from linear, multi-level, selectorless Resistive Random Access Memory (RRAM) arrays based on a Trans-Impedance Amplifier (TIA) approach is presented and studied. SPICE simulation of the core of the system is performed in order to extract predicted sensitivity to error factors such as non-zero TIA offsets and access resistance. A physical implementation of the system is then tested on a small, 12 × 12 reference array and measured results show its ability to decode absolute resistive states in the range of 1 kΩ-220 kΩ within ≈ 11% tolerance.
