Methods, systems, and devices for techniques for performing write operations are described. A controller of a memory system may generate a first command to write first data to a first set of memory cells of a memory array of the memory system. The controller may transmit the first command to a first buffer of the memory system. The first buffer may receive the first command and may generate the first data based on second data from a first address of a register. The first buffer may transmit the first data to the first set of memory cells, via a first buffer, based on the first command.
