You're going to have to post far better details than "memory timeout issues in production" in order to get any useful responses.
What sort of memory - SRAM? DRAM? SDRAM? Flash? Internal SRAM or external? Internal Flash or external? External Flash, EEPROM, NAND, eMMC, USB Stick? CF Card? You see what I mean about the lack of any details?
You'll have to detail the Production Tests and the Failure Reports from the software at least, if not post large slabs of the production test source code. And the design.
