Abstract
A chip set memory controller having a data strobe mask function is disclosed. The controller includes first through N-th memory modules operated in synchronous with a clock signal outputted from the chip set memory controller, whereby the data outputted from each memory module are masked by a data mask signal outputted from the chip set memory controller, and the operation of the data outputted from each memory module is controlled by a data strobe signal outputted from each memory module, for thereby implementing a reverse compatibility of a DQM function by additionally installing a pin in a DDR SDRAM and masking a data strobe signal.
