Interfacing TTL to CMOS?

So I think I goofed when I ordered my parts for my computer I'm building. I ordered everything TTL EXCEPT for my EEPROM.

Is there any suggested glue logic so that I can use this CMOS EEPROM, or should I just go find a TTL one to use instead....

From what I've read, since it *is* an EEPROM and read only, I won't need to do any voltage translation, but wanted to doublecheck.

Whether the (E)EPROM says it's CMOS or not will probably only affect the power consumption when idle. These memories are never actually TTL anymore.
