Abstract
An apparatus for controlling a dynamic random access memory (DRAM), the apparatus comprising an interface to transmit, over a first plurality of wires, to the DRAM a first code to indicate that first data is to be written to the DRAM and a column address to indicate a column location of a memory core in the DRAM where the first data is to be written. The interface is further to transmit a second code to indicate whether mask information for the first data will be sent to the DRAM. If the second code indicates that mask information will be sent, a portion of the column address and a portion of the mask information are sent after the second code is sent. The interface is further to transmit to the DRAM, over a second plurality of wires separate from the first plurality of wires, the first data.
