512K x 8 static RAMs

[Ken Smith]

I've noticed that the availability of very low power static RAMs seems to
have decreased. Are people just not designing in battery backed RAMs of
any size or something like that?

Hello Ken,

I've noticed that the availability of very low power static RAMs seems to
have decreased. Are people just not designing in battery backed RAMs of
any size or something like that?

That is probably true for many applications. Just walk through Costco or
Walmart and look at the prices for USB memory, SD card etc. 1G costs you
around $60-70, but the smaller versions are really cheap. Flash memory
is the new game. A 512K x 8 flash probably costs less than the backup
battery alone would. Plus you don't have to worry about that battery
leaking after a decade or so.
