I have never seen any. I know they make 8 ns parts as of a few years
ago. They may be making as fast as 6 ns now, but I seriously doubt that
4 ns parts exist. Heck even sync rams barely run at the equivalent to
that, 250 MHz.
Async rams are becoming specialty parts as most apps move to sync rams.
Most current design efforts are in multi-port async rams for comms
work. So don't expect async rams to continue to improve performance.

Hi,
Does anyone know if 4ns ASYNC SRAM is available? I am designing a
system which connects to a 64-bit TS202 tigersharc DSP at a system
clock of 100MHz and in order to get a zero-wait state system I need
4ns ASYNC SRAM.. perferably in a 64-bit package (but highly
unlikely)... I'd be happy to find a 16 bit device and just populate 4
of them.
Any help is appreciated.
