To write or<br>
read from that RAM, I specify opposite corners and then just write word by<br>
word. Real easy, fast (40mb/s) and no extra address lines required. Great<br>
for temporary storage/buffer space.<br>
<br>
Does anyone know of a RAM chip that does this all on its own? i.e. write a<br>
command that specifies an 'address' and then write or read until done? I'd<br>
prefer something with less than the 1776 pins the TFT controller chip has<br>
on it!! (say 16 data, command/data, read/write, chip enable & reset).<br>
<br>
Would be real handy on small micros (and even not so small ones that have<br>
100k-200k of RAM)<br>
