2114 is a 1k x 4 bit Static RAM
HM-6513 is a 512 x 4 bit Static RAM
And they have different pinouts.
You can probably wire up some kind of adapter to use the 2114 in place of it. Look at the Y connection on the 6513 and see what it's connected to. And tie the highest address line on the 2114 to ground through a 100 ohm resistor so you are only using the bottom half of the chip.
