Systems and methods for adaptive error-correction coding

Abstract

A storage module is configured to store data segments, such as error-correcting code (ECC) codewords, within an array comprising a plurality of columns. The ECC codewords may comprise ECC codeword symbols. The ECC symbols of a data segment may be arranged in a horizontal arrangement, a vertical arrangement, a hybrid channel arrangement, and/or vertical stripe arrangement within the array. The individual ECC symbols may be stored within respective columns of the array (e.g., may not cross column boundaries). Data of an unavailable ECC symbol may be reconstructed by use of other ECC symbols stored on other columns of the array.

What is claimed is:  
     
         1 . An apparatus, comprising:
 an error-correcting code (ECC) write module configured to generate a plurality of ECC codeword symbols comprising data of a storage request;   wherein the ECC codeword symbols are configured for storage within respective columns of a solid-state storage array, each column comprising one or more solid-state storage elements; and   an adaptive write module configured to stream the ECC codeword symbols comprising the data of the storage request to respective columns of a set of two or more columns of the solid-state storage array.
