Abstract:

Static Random Access Memories (SRAMs) are considered a major bottleneck in high performance System-on-Chip (SoC) design and there is a large demand for high performance SRAMs with minimal energy consumption. Time speculation techniques such as Razor ease timing guardbands to improve performance or reduce energy consumption. The state-of-the-art approach has high area and energy overheads due to the error detection logic. This study proposes a timing speculative SRAM that extends the existing Replica Bitline Column to detect read timing failures. We also extend the SRAM decode logic to protect from incorrect write operations. We demonstrate our Replica-based Timing Speculative SRAM (RTS) is an energy and area efficient design alternative to prior techniques such as Razor. Our proposed design is 22% to 58% more energy efficient in reading operations and it has an error detection mechanism which is 35% to 73% more area efficient that Razor-enabled SRAM.
