Abstract
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 and detected using ECC techniques on a zero prefixed data block that is read out of the memory. This allows a memory subsystem to be optimized for bandwidth and latency depending upon this application.
