Systems and methods for adaptive error-correction coding

A method comprising:

• determining a storage location of requested data stored in an adaptive channel configuration of solid-state storage elements of a solid-state storage medium by identifying two or more independent storage channels comprising a set of error-correcting code (“ECC”) codeword symbols corresponding to requested data, wherein each independent storage channel of the two or more independent storage channels comprises two or more of the solid-state storage elements;
• issuing a command to the solid-state storage memory to read the set of ECC codeword symbols from the identified two or more independent storage channels according to the adaptive channel configuration;
• and
• extracting, from the solid-state storage memory, the set of ECC codeword symbols from the identified two or more independent storage channels.

An apparatus comprising:

• a solid-state storage memory comprising a plurality of storage cells configured in a solid-state storage array;
• an adaptive solid-state storage controller communicatively coupled to the solid-state storage memory;
• and
• a processor configured to execute instructions stored in a memory causing the apparatus to determine a plurality of different independent storage channels for storing a plurality of error-correcting code (“ECC”) codeword symbols in the solid-state storage memory, wherein each of the plurality of different independent storage channels is determined based on an adaptive channel configuration and comprises two or more solid-state storage elements of the solid-state storage array;
• the adaptive solid-state storage controller:
• arranging a set of the plurality of ECC codeword symbols for storage in one of the plurality of different independent storage channels according to the adaptive channel configuration, and
• issuing a command to the solid-state storage memory to store the set of ECC codeword symbols in the one of the plurality of different independent storage channels according to the adaptive channel configuration;
• and
• the solid-state storage medium storing the set of ECC codeword symbols in the one of the plurality of different independent storage channels according to the adaptive channel configuration.
