I have got the DS1971 256-Bit EEPROM iButton today.

While connected to the 1-Wire bus, the owfs shows following:

r...@ubuntu810:/usr/local/tridicka/1wire/uncached/14.AC5755040000# ls -l

-r--r--r-- 1 root root  16 2010-08-17 11:37 address
-r--r--r-- 1 root root 256 2010-08-17 11:37 alias

-r--r--r-- 1 root root  16 2010-08-17 11:37 r_address
-r--r--r-- 1 root root  12 2010-08-17 11:37 r_id
-r--r--r-- 1 root root  16 2010-08-17 11:37 r_locator
-r--r--r-- 1 root root  32 2010-08-17 11:37 type

I just wonder, why is the memory file size 16-bytes only (see above).
In the owfs It is possible to read/write 16 bytes from/to the "memory" file
only.

In the Maxim sheets
<http://www.maxim-ic.com/datasheet/index.mvp/id/2823>the DS1971 is
described as 256-bit and on the OWFS
web <http://owfs.org/index.php?page=standard-devices> as a 32B device.

Am I missing or overlooking something?

Thanks for hints
