I, Robot RAM?

Sorry about the previous "send too quick".
 
The manual lists the RAM on the I, Robot Video PCB in rows 11 & 12 as:
Type 4164-15 Integrated Circuit
 
However, on the actual chip from MT, they are marked 4264-15.
 
Looking for a verification if these are the same thing.  Maybe 4264 was MT's internal part number for generic 4164 RAM?
 
Anyone?
