[sdiy] New SPI SRAM

[Richie Burnett]

ISSI website is showing an interesting new half-Megabyte 8-pin serial (SPI) 
Static RAM chip that might be of interest for audio processing:

I've had Microchip's 23LC1024 (128 Kilobyte SPI SRAM) working with dsPIC 
using SPI via DMA,  so have requested a few samples of the ISSI part to try 
it out.
