Error Correction Codes (ECC) play an essential role in safeguarding memory systems by detecting and correcting errors that arise from various sources, including ...
As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to ...
For the uninitiated, low-density parity-check (LDPC) code is an error correction code (ECC) that is used to both detect and correct errors on data that is transmitted ...
When running a server, especially one with mission-critical applications, it’s common practice to use error-correcting code (ECC) memory. As the name suggests, it uses an error-correcting algorithm to ...
Hybrid Active-Reactive Profiling (HARP), a new error profiling algorithm that rapidly achieves full coverage of at-risk bits in memory chips that use on-die ECC ...
When the data is read back from the flash memory and passed into the error-correction module, the decision of which bits are erroneous is based solely on the redundant information added into the ...
The FEC on a CD uses interleaving and layering. A short {32, 28} code is used to correct errors read from the track. Any it cannot correct are marked as erasures and the result is de-interleaved. The ...
Several techniques can be used to efficiently implement a Hamming coder for single-bit error correction and double-bit error detection. Many error-correcting codes ...
This article describes the idea of generating synthesizable IP core by a software tool taking an error correction algorithm of BCH (Bose-Chaudhuri-Hocquenghem) as an ...
