Abstract
A method performed by a controller of a solid state drive (SSD) comprising receiving from a host a write request to store write data in a nonvolatile semiconductor storage device of the SSD. The method also comprises identifying a first codeword and a second codeword stored in the nonvolatile storage device, the first codeword and the second codeword configured to store write data corresponding to the write request. Responsive to the write request, the method comprises writing a first portion of the write data to the first codeword and writing a second portion of the write data to the second codeword, and sending a message to the host once the write data has been written to the nonvolatile semiconductor storage device. The first and second codewords are adjacently stored, and the write data has a length that is greater than the length of the first and second codewords.
