WebSep 6, 2011 · LDPC ECC in NAND flash memory. As raw BER in NAND flash increases to close to 10-2 at its life end, hard-decision ECC, such as BCH code, is not sufficient any more, and such more powerful soft-decision ECC as LDPC code becomes necessary. The outstanding performance of LDPC code is based on soft-decision information. WebError-Correcting Code (ECC) memory has also been incorporated on certain PIC32 devices, which extends the usable life of the Flash memory. 52.1.2.1 FLASH PARTITIONS Each bank of Flash memory is divided into two logical Flash partitions: the PFM and the BFM (some PIC32 devices have two BFM partitions).
