Abstract
A solid state drive (SSD) device includes a memory having a plurality of memory cells and an encoder configured to encode information using a polar code to generate encoded information to be stored in the memory. The polar code is constructed based on a plurality of channel models corresponding to different read channel scenarios, including at least a first channel model corresponding a first read channel scenario and a second channel model corresponding to a second read channel scenario, the second read channel scenario different from the first read channel scenario. The SSD device also includes a controller configured to write the encoded information to memory cells in the memory, and read the encoded information from the memory cells in the memory using a selected one of the first read channel scenario and the second read channel scenario.
