Abstract:
1. A method, comprising: programming a first On-Die Termination (ODT) value into a first plurality of dynamic random access memory (DRAM) devices on a dual inline memory module (DIMM); and programming a second ODT value into a second plurality of additional DRAM devices on the DIMM, wherein the first and second ODT values are not the same value; wherein the first ODT value is stored in an Extended Mode Register (EMR) on each of the DRAM devices comprising the first plurality of DRAM devices, and wherein the second ODT value is stored in an EMR on the each of the DRAM devices comprising the second plurality of additional DRAM devices; and wherein the first plurality of DRAM devices comprises a plurality of non-error checking and correction (non-ECC) DRAM devices and the second plurality of additional DRAM devices comprises a plurality of ECC DRAM devices.
