Flash Memory LDPC
LDPC corrects errors caused by flash storage failure mechanisms. The data is encoded while writing into the storage devices and it is decoded while reading from the storage devices. Decoding corrects read errors. The LDPC code that is used with storage devices should exhibit very low error floor (very low BER) and have high throughput.
