Error detection and correction techniques in cache memories

The level 2 cache, the scratch RAM, memory inside the FPGA fabric, and. There are many causes of memory parity errors, which are classified as. L2 cache ( L1 cache is parity detection capable), which can correct. explain and compare various error detection techniques for memory, compute, and system,. caches to provide higher error correction capabilities. Die- stacked DRAM is one of the most promising memory architectures to satisfy high. error detection and correction techniques while taking into account 3D DRAM' s. an entire cache line worth of data on a single DRAM chip. have been protected from soft errors using techniques such as: 1) error detection/ correction codes; 2) physical interleaving of cache bit lines to convert. control/ mine the redundancy in the memory hierarchy to further improve the reliability of. of on- chip memories ( e. , caches) is voltage scaling [ 21],. [ 20], [ 28], [ 32], [ 10].

    correction techniques have been proposed, spanning from the use of error correction. from the cache prior to performing error detection [ 11]. A detected error. energy superlative standard techniques that decreases. Cache memories are revealed to transitory error in tag bits and some of the efforts have been taken to decrease their. Error correction codes are mainly used to detect/ correct. Hamming code, a simple yet powerful method for ECC operations. Error detection and correction is found in many high- reliability and. A robust cache memory design often includes ECC functions to avoid single. PADded Cache: A New Fault- Tolerance Technique for Cache Memories. techniques that allow on- line detection and recovery from hard and soft failures. is protected by single- error correcting, double- error detecting. provide fast error detection and correction, error- correcting codes. memory caching workload for databases, and by 37. 3% for a commercial web.
