A 32-bit mode operation for a typical 64-bit ECC memory subsystem. In 32-bit mode, each data block will have an 8-bit ECC value, which is consistent with ECC values generated for 64-bit data. This is achieved by prefixing the data with 32 zeroes. When reading out data, memory faults can be corrected...http://www.google.com.au/patents/US6216247?utm_source=gb-gplus-sharePatent US6216247 - 32-bit mode for a 64-bit ECC capable memory subsystem
