    摘要: A device reduces false positive memory error detections by using a masking unit and sensitivity mask data to exclude unused portions of the memory from the error detection computations. A device includes an error detection unit to read data from the memory and verify data integrity. The sensitivity mask data indicates unused portions of the memory. Unused portions of the memory may correspond with configuration data for unused portions of a programmable device. Each bit of the sensitivity mask data may indicate the usage of one or more bits of the data from the memory. In response to the mask data, the masking unit sets data from the unused portions of the memory to values that do not change the result of the error detection computations. This prevents any errors in data from the unused portions of the memory from raising an error signal.

    摘要: Distributed random access memory in a programmable logic device uses configuration RAM bits as bits of the distributed RAM. A single write path is used to provide both configuration data and user write data. Selection circuitry, such as a multiplexer, is used to determine whether the single write path carries configuration data or user write data. In another aspect of the invention, the configuration RAM bits are used as to construct a shift register by adding pass transistors to chain the configuration RAM bits together, and clocking alternate pass transistors with two clocks 180° out of phase with one another.
