چکیده

This paper proposes a 7T SRAM that realizes a blocklevel instantaneous comparison feature. The proposed SRAM is useful for operation results comparison in dual modular redundancy (DMR). The data size that can be instantaneously compared is scalable using the proposed structure. The 1-Mb SRAM comprises 16-Kb blocks in which 8-Kb data can be compared in 130.0 ns. The proposed scheme reduces energy consumption in data comparison to 1/418, compared to that of a parallel cyclic redundancy check (CRC) circuit.

A Low-Latency DMR Architecture with Efficient Recovering Scheme Exploiting Simultaneously Copiable SRAM

This paper presents a novel architecture for a fault-tolerant high-performance system using a checkpoint/restart approach with dual modular redundancy (DMR). The proposed architecture can perform low-latency copy with instantaneously copiable SRAM. Furthermore, we can use an instantaneous comparison scheme that has more fault coverage than comparison with a cyclic redundancy check (CRC). Evalua...

7T SRAM Enabling Low-Energy Instantaneous Block Copy and Its Application to Transactional Memory

This paper proposes 7T SRAM which realizes block-level simultaneous copying feature. The proposed SRAM can be used for data transfer between local memories such as checkpoint data storage and transactional memory. The 1-Mb SRAM is comprised of 32-kb blocks, in which 16-kb data can be copied in 33.3 ns at 1.2 V. The proposed scheme reduces energy consumption in copying by 92.7% compared to the c...
