Write redirect

A data storage device includes a memory (including a single level cell (SLC) memory portion and a multilevel cell (MLC) memory portion), a plurality of data latches, and routing circuitry coupled to the plurality of data latches. The routing circuitry is configured to cause write data, received from a controller, to be stored at a data latch of the plurality of data latches. The routing circuitry is further configured to cause the write data to be copied from the data latch to a particular portion of the memory based on receiving a program mode command after the write data is stored at the data latch, where the program mode command indicates the particular portion as one of the SLC memory portion or the MLC memory portion.
