'[EE] SRAM'

So is SRAM as an "external" storage method dying off?

Does anyone know of a company which is still making,
and plans to keep making, SRAM?  Low density parts,
say 1-4 Mbit?

Why?
To my knowledge, no memory technology is as fast as
SRAM... I doubt if even the most advanced DRAM chips
can beat 10ns...

I do not think so. I've seen many designs still using external
SRAMs as well as external Flash and EEPROMs.

Cypress, Renesas, IDT, NEC, and Samsung all make SRAM.

I doubt that SRAM will go away anytime soon.

BSI and ISSI both make 8Mbit and smaller SRAM parts.  They are coming
out with even lower voltage versions (1.8v) so they are continuing to
make "new" SRAM parts, not just maintaining their old lines.

SRAM still has a few distinct advantages (relating to performance and
ease of integration) over other memory types.  These aren't going to
be eclipsed anytime soon.

Isnt Infion still making sram? and Micron?  There are others.....I havent had one on a design for a few years, but I've had reps come in show me the lines.
 
 So yes, they are still there...not sure if there is much at 5V these days...most migrating to 3.3V and lower.

Alliance makes them as well.  http://www.alsc.com/  --fairly good pricing...

Check your availability if you decide to use Cypress...  Some components
are tough to source at the moment.

SRAM is used for cache memory in PCs (among other
things), so I doubt the technology will die out unless
someone finds a process that makes DRAM an order of
magnitude faster than it is at present!
