TL;DR
This paper introduces an open-source memory compiler integrated within Cadence Virtuoso for automated RRAM generation, layout, and verification, addressing a gap in academic tools for resistive memory design.
Contribution
It presents the first open-source RRAM memory compiler that automates design, layout, and physical verification within a popular EDA environment, including a novel RRAM architecture.
Findings
Capacitance of control lines is 5.83, 3.31, and 2.48 fF per cell.
Resistance of SEL line is 1.28 Ohm per cell.
Worst case parasitics and settling times are evaluated.
Abstract
The lack of open-source memory compilers in academia typically causes significant delays in research and design implementations. This paper presents an open-source memory compiler that is directly integrated within the Cadence Virtuoso environment using physical verification tools provided by Mentor Graphics (Calibre). It facilitates the entire memory generation process from netlist generation to layout implementation, and physical implementation verification. To the best of our knowledge, this is the first open-source memory compiler that has been developed specifically to automate Resistive Random Access Memory (RRAM) generation. RRAM holds the promise of achieving high speed, high density and non-volatility. A novel RRAM architecture, additionally is proposed, and a number of generated RRAM arrays are evaluated to identify their worst case control line parasitics and worst case…
