Method for ECC-equivalent memory using non-ECC DIMMs

Disclosed is a method for error checking and correction-equivalent (ECC-equivalent) memory using non-ECC direct in-line memory modules (DIMMs). Benefits include improved board design.

Background

              ECC memory, DIMMs, and SO-DIMMs are more expensive and less available than standard memory, DIMMS, and SO-DIMMs.

Description

              The disclosed method is ECC-equivalent memory using non-ECC DIMMs on a single board computer (SBC). The method is comprised of the following components:

·        SBC

·        Non-ECC memory DIMMs

·        Memory chips

              Instead of using ECC memory DIMMs, ECC circuitry (with standard memory chips) is designed onto the SBC motherboard and non-ECC DIMMs are used for memory (see Figure 1). This configuration results in a memory configuration equivalent to using ECC DIMMs.

              The non-ECC DIMMS can be standard DIMMs or small outline DIMMs (SO-DIMMs).

Advantages

              Some implementations of the disclosed structure and method provide one or more of the following advantages:

·        Avoids availability issues

·        Results in cheaper board design
