TECED: A Two-Dimensional Error-Correction Codes Based Energy-Efficiency SRAM Design

Abstract

The reliability of memory is an important issue. The rapid development of transistor technology makes the memory more prone to soft errors. Several recent efforts have proposed various designs to avoid the corruption of stored data by using Error Correction Codes (ECC). However, these designs tend to focus on one indicator, which means they cannot balance the electrical timing, area and power consumption constraints with the increasing of the chip-scale and the operating frequency. In this paper, we propose a design named TECED: A Two-Dimensional Error-Correction Codes Based Energy-Efficiency SRAM Design. We achieve higher energy-efficiency and lower hardware cost by using a two-dimensional error correction codes, and evaluate the design by considering the overall system performance. Comparing with the traditional Hamming code, the evaluation shows that the TECED reduces most of fifty percent of the area overhead and twenty-eight point five percent power consumption of the memory at a specific storage capacity.

Development of the method of detecting and correcting data transmission errors in IoT systems for monitoring the state of objects

“…The introduction of codes with the possibility of detecting and correcting errors also occurs in the development of semiconductor RAM with random access. In [7], a variant of RAM construction in the form of a two-dimensional energy-efficient structure based on the use of error correction codes is proposed. The proposed method is based on the use of the Hamming code.…”

“…Work [16] contains an overview of various error correction methods, including the Hamming code. It is specifically stated that the Hamming code (7,4) is used to correct a single error. The extended Hamming (8,4) code has an extra bit and is used for single error correction as well as double error detection.…”

Error mitigation in LPWAN systems: A study on the efficacy of Hamming-coded RPW

“…The strategic use of Hamming codes in low-noise environments can achieve reliable data transmission with less power than more complex methods [ 22 ]. The study in [ 23 ] positioned Hamming codes as a potential standard due to their balance between power consumption and error correction capabilities. Conclusively, the combination of simple hardware implementation, strategic application in low-noise scenarios, and potential as a low-power design baseline makes Hamming codes an asset in achieving energy efficiency.…”
