[SOLVED] Why SRAMs need SI pins?

[Qwerty112233]

How does this case work? Why are DFT and MBIST both hooked up to SRAMs ?

Sorry if this sounds vague, I don't know much about dft/mbist.

A good boundary scan implementation ought
to encompass every digital / mixed-signal part
on the board. It may not be about the SRAM at
all, other than wanting to know that every pin
is indeed connected. If the customers want that
testability enough to pay for it, the vendors
will provide it.
