using a TFT LCD which has over 300k of RAM in it. 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>
