Memory component having internal read-modify-write operation

Abstract:

An memory component includes a memory bank and a command interface to receive a read-modify-write command, having an associated read address indicating a location in the memory bank and to either access read data from the location in the memory bank indicated by the read address after an adjustable delay period transpires from a time at which the read-modify-write command was received or to overlap multiple read-modify-write commands. The memory component further includes a data interface to receive write data associated with the read-modify-write command and an error correction circuit to merge the received write data with the read data to form a merged data and write the merged data to the location in the memory bank indicated by the read address.
