Abstract
A memory interface controller employs a DATUM multiplier within a destination address to perform DATUM RAID operations. If destination data is in an XOR memory address space, then the multiplier can indicate to multiply source data by the multiplier and XOR that resulting data with the destination data. The DATUM multiplier can be read in response to detection of a memory command. The multiplier alternatively can be used in connection with an input/output bus write command to write source data from the input/output address space to an XOR memory address space. In response to such a write command, the input/output bus data in the input/output address space is multiplied by the multiplier; that resulting data is XORed with the destination data in the XOR memory address space. The multiplier in this case can be within an input/output bus address associated within the input/output bus data.
