Apparatus and associated method for transferring data to memory, such as resistive sense memory (RSM). In accordance with some embodiments, input data comprising a sequence of logical states are transferred to a block of memory by concurrently writing a first logical state from the sequence to each of a first plurality of unit cells during a first write step, and concurrently writing a second logical state from the sequence to each of a second non-overlapping plurality of unit cells during a second write step.
