The incoming write request comprises a write command to transfer write data to a buffer memory. An initial portion of the write data is written to the buffer memory. An alignment of a final portion of the write data with respect to a memory bank width of the buffer memory is determined. The client is determined to be designated as a burst-overwrite client. In response to determining that the final portion of the write data is unaligned with the memory bank width of the buffer memory, the final portion of the write data is written to the buffer memory without preserving previously stored data based on the client being designated as a burst-overwrite client. ## Claims ### Claim 1 A method comprising: designating each client of a buffer memory as either a burst over-write client or a data preserving client based on a function performed by each client;
