  • Structure and method for managing available memory resources
    Patent number: 6907508
    Abstract: In a digital data processing system having a memory component, a structure and method for managing available memory resources. Free pointers to respective free memory blocks are stored in memory blocks maintained as a linked list. In a system having a hierarchically-organized memory component, a small number of the free pointers are maintained at a relatively higher performance level of the memory and the balance of the free pointers are maintained at a relatively lower performance level of the memory.
    Type: Grant

  • Method and apparatus for improving noise immunity in a DDR SDRAM system
    Patent number: 6785189
    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.
