Abstract
A system and method for transmitting commands from one or more input/output devices to a memory is provided. An identification tag is appended to each command to define the command as either a read or write command. The read commands are separated from the write commands based on the state of the identification tag, and the read and write commands are separately queued. The read commands are stored in a first command queue, and the write commands are stored in a second, separate, command queue. The read commands in the first command queue are successively transferred to the memory upon completion of the current memory read function, and the write commands in the second command queue are successively transferred to the memory upon completion of the current memory write function. The transfer of the read and write commands is independent.
