Thanks, but this is standard parallel memory; that 32k SRAM takes 16 lines for addressing, 8 for data, and 3 more for control, which uses roughly 100% of available I/O on the arduino.
I guess I could make my own "SPI SRAM" by using a dedicated ATmega8 in SPI slave mode and a typical SRAM, but I'm hoping for something a bit simpler.
thanks,
