For a project, We need support for DDR3 connectivity (with register functionality) for following cases for P3041 Processor -

Case (1) How would we connect DDR3 Memory chip (without ECC Functionality) to P3041 Processor (using ECC Functionality of Processor) , and

Case (2) How would we connect DDR3 Memory (with ECC Functionality) to P3041 Processor (without using ECC Functionality of Processor).

We would not be using DIMM connectivity in either of the cases . Pls elaborate direct pin to pin connectivity.

We would be using16 bit memories for both cases.

In Case(1), we will use 72 bit (64 + 8 ECC Bits) interface of the P3041 ,thus requiring 5 memory chips (without ECC functionality). Only 8 bits of 5th memory chip shall be used (4x16+8)

In Case (2) we will use 64 bit interface of processor , thus requiring 4 memory chips (with ECC Functionality)
