I work in networking. SRAMs are used extensively. There are many
applications where SDRAM access times are not enough.

In that case someone ought to update 
http://wiki.slimdevices.com/index.cgi?SLIMP3ClientProtocol
since it states
".. buffer chip is a 128K x 8 (1Mbit) SRAM. It is presented to the
server as a 64K x 16 circular buffer .."

Provenly untrue. See

In my field, ECC has become a new requirement in the last 4 years
because of true issues and instabilitieds caused by occasional flipped
bits. There are enough IEEE articles on it to fill a bookshelf.

It does, and has, and continues to happen. The key is to detect most
errors, but no error detection scheme is utterly immune to overy
possible combination of errors. CRC definitely isn't. Highe rleve
protocols may detect the error, sometimes via check, sometimes the hard
way via a diagnosed problem. The computer infrastructure underneath
works fine most of the time despite occasional flipped bits, which are
an everyday reality as we transport information, and are detected and
corrected most of the time.

What I was asking is data on errors during transmission from audio CD
to computer. Thanks for going on a tangent and telling me I am an
ignorant sod.
