Abstract

Official abstract text for this publication.

A data storage device includes a non-volatile memory and a controller including a first error correction coding (ECC) engine configured to generate a first codeword corresponding to data to be stored at the non-volatile memory. The data storage device also includes a second ECC engine coupled to the controller and to the non-volatile memory. The second ECC engine is configured to receive a representation of the first codeword from the controller and to perform a decode operation of the representation of the first codeword to correct transmission errors prior to storage of the data in the non-volatile memory.

First claim

Opening claim text (preview).

What is claimed is: 1. A data storage device comprising: a non-volatile memory; a controller including a first error correction coding (ECC) engine configured to generate a first codeword corresponding to data to be stored at the non-volatile memory; and a second ECC engine coupled to the controller and to the non-volatile memory, wherein the second ECC engine is configured to receive a representation of the first codeword from the controller and to perform a decode operation…
