[sdiy] SRAM question

Ok, so I fund a Flash Ram chip and looked at the pin out and it looks like it works the same way as the SRAM as far as data I/O and Addressing. So the thing doesn't need any backup power supply?

What I'm doing is going back to an idea I had a while ago about using a RAM chip in conjunction with a bank of switches (or an Arduino with a rotary encoder) and a DAC to make a user programmable wave table. This is based off of an idea in Electro Notes. 

Other uses for this could be a song programmer or a very very long sequencer all dependent on how fast the output is clocked. I think 8 bits is more than enough resolution for Analogue.
