If you bought the kit from Amazon, i don't believe it comes the memory card. you will have to buy the SD memory card separately. some other vendors may throw in a free bag or memory card but Amazon doesn't give these items out as part of the "kit". hope this helps.
Canon never includes memory cards for DSLRs (althouth they normally include it for point and shoot camera). My 6D is fine with SanDisk 45MB/s card; lower speed might have problem in video or rapid shooting.
