[chbot] SRAM with auto addressing

[Andrew Errington]

FRAM? Never used it, but it might do what you want.

Here's a simple example from some guy on the internet whom I have never met:

I've been using a TFT LCD which has over 300k of RAM in it. To write or
read from that RAM, I specify opposite corners and then just write word by
word. Real easy, fast (40mb/s) and no extra address lines required. Great
for temporary storage/buffer space.

Does anyone know of a RAM chip that does this all on its own? i.e. write a
command that specifies an 'address' and then write or read until done? I'd
prefer something with less than the 1776 pins the TFT controller chip has
on it!! (say 16 data, command/data, read/write, chip enable & reset).

Would be real handy on small micros (and even not so small ones that have
100k-200k of RAM)
