PROJECT TITLE :

A Study on the Programming Structures for RRAM-Based FPGA Architectures

ABSTRACT:

Field Programmable Gate Arrays (FPGAs) will benefit non-volatility and high-performance by exploiting Resistive Random Access Reminiscences (RRAMs). In RRAM-based mostly FPGAs, the recollections do not solely replace the SRAMs and store configurations, but they'll additionally replace the transmission gates and propagate datapath signals. The high-performance achievable by RRAM-primarily based FPGAs comes from the fact that the on-resistance of the memory devices is smaller than the equivalent resistance of a transmission gate. Efficient programming structures for RRAMs ought to give high current density with a tiny space footprint, to obtain a low . During this paper, we initial examine the efficiency of the widely-used 2Transistor/1RRAM (2T1R) programming structure and establish four major limitations of the 2T1R structure. To overcome these limitations, we tend to propose a 2Transmission-Gates/1RRAM (2TG1R) and a 4Transistor/1RRAM (4T1R) programming structures. We tend to perform both theoretical analysis and electrical simulations on the evaluated programming structures. 4T1R programming structure is the most effective in terms of current density with one.4 and one.one as compared to 2T1R and 2TG1R counterparts, respectively. We tend to also investigate the result of boosting the programming voltage of the programming structures. Experimental results show that boosting for all the programming structures improves driving current of the evaluated programming structures by three and area efficiency by one.7 on average.
