Hi,
I want to interface 8 separate memory chips (not a single module like DIMM) with T1042. Moreover, i want to use the ECC option provided by the DDR memory controller of T1042. The issue is that i have not found any single DDR3 Chip having option of ECC. So how can i make use of the ECC option?
Should i interface an extra chip as done in DIMM?
Have a great day,
Yes, you should use the additional memory chip. If you are going to use 8 of 8-bit DDR memory chips for data then you should add the same 8-bit DDR memory chip for the ECC. It should be conected to the dedicated ECC byte lane of the T1042 DDR controller. Here picture for such case I extracted from the T040 reference manual.
