A semiconductor device may include a memory bank and a plurality of mode registers that communicatively couple to each of the plurality of memory banks. The plurality of mode registers may include a pattern of data stored therein. The semiconductor device may also include a bank control that receives a write pattern command that causes the bank control to write the pattern of data into the memory bank, send a signal to a multiplexer to couple the plurality of mode registers to the memory bank, and write the pattern of data to the memory bank via the plurality of mode registers.
