Abstract:
1. A method for handling read and write operations of Read-Modify-Write (RMW) commands in a memory system containing a plurality of Extreme Data Rate (XDR) Dynamic Random Access Memories (DRAMs), comprising: storing write operation data in a write buffer, wherein the write operation data is less than a cacheline of data in length; performing a read operation; storing read operation data in a RMW buffer, wherein the read operation data is at least one cacheline of data in length; merging the read operation data and the write operation data to form a full cacheline of data; storing the merged data in at least one of the plurality of XDR DRAMs; and executing at least one of a read command or a write command in the time between performing the read operation and the storing of the merged data in the at least one of the plurality of XDR DRAMs.
