Memory devices may perform read operations and write operations with different bit error correction rates to satisfy a bit error correction rate. However, improving the bit error correction rate of the memory device using a single type of read command and/or write commands may result in longer read and write commands. Moreover, using longer read and write commands may result in undesirable higher memory power consumption and may reduce memory throughput. Accordingly, memory operations are described that may use combination of commands with increased bit error correction capability and reduced bit error correction capability. For example, the read operations may use multiple (e.g., at least two) sets or groupings of read commands and the write operations may use multiple (e.g., at least two) sets or groupings of write commands.
