Extending Arduino Uno RAM

The Arduino Uno has only 2kB of RAM for both program variables and program data making it a precious resource which can be quickly filled.  In programs that require additional storage an external RAM chip can be used to extend the usable storage space.  This video discusses using a Microchip 23LC1024 serial RAM chip to create this extra storage.

A document that fully explains both the wiring of the chip and the example program is here:

The Arduino sketch for the example program is here:

Dave Dubins has created a library of functions based upon the sketches in this tutorial.  Here is a link to the library:  https://github.com/dndubins/SRAMsimple
