I have a board with the LDM and UDM pins swapped. If they are tied to low, will the memory still 'work', given that data is always written to mod 4 addresses and always using all 4 bytes?
Memory is Micron MT47H32M16HR-25E.
Yes. Since the read and writes aren't dependent on those signals, you are correct. Specifically there is no requirement that the signals transition; they can stay at a static enabled
