This paper presents measurement results of bit error rate (BER) and soft error rate (SER) improvement on 150-nm FD-SOI 7T/14T (7-transistor/14-transistor) SRAM test chips. The reliability of the 7T/14T SRAM can be dynamically changed by a control signal depending on an operating condition and application. The 14T dependable mode allocates one bit in a 14T cell and improves the BER in a read ope...

Due to shrinking feature sizes and decreasing supply voltages in current technology scaling trends, the reliability of circuit would be affected by radiation induced particle hits. Nowadays soft errors are main factor in reliability degradation of logic circuits, which have been a great concern in memories also. Here, we present a systematic and integrated methodology for circuit robustness to ...

“Amplify and Forward” and “Decode and Forward” are the two main relaying functions that have been proposed since the advent of cooperative communication. “Soft Decode and Forward” is a recently introduced relaying principle that is to combine the benefits of the classical two relaying algorithms. In this work, we thoroughly investigate soft relaying algorithms when convolutional or turbo codes ...

| TURBO-BLAST is a novel multi-transmit multi-receive (MTMR) antenna scheme for highthroughput wireless communications. It exploits a novel space-time coding scheme based on the independent block forward error correction (FEC) codes and space-time interleaving, and a near optimal iterative decoder, for decoding a new generation of space-time codes. The proposed iterative decoder has two decodin...

Abstract—To combat the effect of intersymbol interference (ISI) while transmitting data over an ISI channel in a coded data transmission system, the impulse response of the channel is required. As part of the turbo equalization approach, which facilitates iterative equalization and decoding, we introduce a method to iteratively improve the quality of the estimate of the channel characteristics....

Resilient computation has been an emerging topic in the field of high-performance computing (HPC) for several years. In particular, studies show that tolerating faults on leadershipclass supercomputers (such as exascale supercomputers) is expected to be one of the main challenges. In this paper, we utilize dynamic binary instrumentation and virtual machine based fault injection to emulate soft ...

The raw bit error rate of NAND Flash memory increases as the semiconductor geometry shrinks for high density, which makes it very necessary to employ a very strong error correction circuit. The soft-decision-based error correction algorithms, such as low-density parity-check (LDPC) codes, can enhance the error correction capability without increasing the number of parity bits. However, soft-dec...

The performance of algebraic soft-decision decoding (ASD) of Reed-Solomon (RS) codes using bit-level soft information is investigated. Optimal multiplicity assignment strategies (MAS) of ASD with infinite cost are first studied over erasure channels and binary symmetric channels (BSC). The corresponding decoding radii are calculated in closed forms and tight bounds on the error probability are ...

Reed-Solomon (RS) codes have been used for a long time in many data storage systems for error correction. Popularity of RS codes is due to their powerful burst error correction capability and well-established decoding algorithm with efficient hardware implementation providing high throughput. Conventional hard-decision decoding algorithms are able to correct up to half the minimum distance. To ...
