Abstract
In a memory controller for use with a DDR SDRAM, an apparatus improves the immunity of the controller to noise glitches on the DQS signal provided by the DDR SDRAM during READ operations. A method adjusts the noise immunity provided by the apparatus. In particular DQS quality circuits frame the DQS signal for a predetermined portion of the READ operation.
