A host device may generate one or more codewords associated with data to be stored in the memory device. In some cases, the host device may generate one or more codewords for error detection and correction (e.g., corresponding to data transmitted by the host device to the memory device). In some cases, the host device may transmit the codewords and the associated data using an extended (e.g., adjustable) burst length such that the one or more codewords may be included in the burst along with the data. Additionally or alternatively, the host device may transmit one or more of the codewords over one or more channels different than the one or more channels used to transmit the data. ## Claims ### Claim 1 A method, comprising: identifying a first set of data for communicating over a first channel between a memory device and a host device, the first channel associated with a channel width and the first set of data corresponding to a first burst length;
