Abstract:
A method of writing data to a memory device comprising the steps of:receiving an address of said memory device into which said data is to be written; decoding said address to determine a location of said memory device associated with said address; receiving said data, wherein the data comprises a plurality of bytes received in synchronization with a synchronization edge of an external clock signal; receiving a data mask signal for at least a portion of said data; activating a column line for each location of said memory device associated with an address for said data for which a data mask signal is not received to write said data for which a data mask signal is not received into said memory device; and not activating a column line for each location of said memory device associated with an address for said at least a portion of said data for which said data mask signal is received to prevent said at least a portion of said data for which said data mask signal is received from being written to said memory device.
