user31105: I'm intending to try a LP621024D70LL (128 KB SRAM memory, 32 pins) on an Arduino Mega.
However, I now see there is no library for it ... I wonder how hard it is to access it? I can miss 32 digital pins (the Mega has enough), however, I'm a bit worried about having to write a library, especially since I do not have any gear like an oscilloscope.
Would it be easy to use the library of the more knwn 32K256 or 23LC1024 as basis? (where I also have no experience with btw).

user4143: That's so old I can't find a datasheet for it. If you know the pinout then you know more than me at the moment. Chances are it's a standard 8-bit CPU interface. 

Writing:

Set the address on the address pins, set the data to write on the data pins, enable the chip, and pulse WR.

Reading:

Set the address on the address pins, enable the chip, and while pulsing the OE pin read the data pins.
And no, you can't really use a serial SRAM chip library as a basis - the operation is completely different.
