Adaptive generalized concatenated codes for low power ECC with varying overhead

A device for encoding information bits for storage in a storage device, the device comprising:

• a memory interface configured to communicate with the storage device;
• and
• at least one processor configured to:
• obtain the information bits;
• encode the information bits using a first code to obtain a first plurality of code words;
• transform the first plurality of code words using a plurality of transformations, wherein each code word from among the first plurality of code words is transformed using a different transformation from among the plurality of transformations;
• encode the transformed first plurality of code words using a second code to generate a second plurality of code words;
• update the first plurality of code words based on the second plurality of code words to generate an adaptive generalized concatenated code (A-GCC) code word;
• and
• control the memory interface to transmit the A-GCC code word to the storage device.

A method for encoding information bits for storage in a storage device, the method being executed by at least one processor and comprising:

• obtaining the information bits;
• encoding the information bits using a first code to obtain a first plurality of code words;
• transforming the first plurality of code words using a plurality of transformations, wherein each code word from among the first plurality of code words is transformed using a different transformation from among the plurality of transformations;
• encoding the transformed first plurality of code words using a second code to generate a second plurality of code words;
• updating the first plurality of code words based on the second plurality of code words to generate an adaptive generalized concatenated code (A-GCC) code word;
• and
• controlling a memory interface to transmit the A-GCC code word to a storage device.
