well, the memory use different localities in which you can write A-0 means the first bit, A-1 de second bit successively you can do different combinations and you can write in these
for example
la location 000000000000
0000000000001
0000000000010
successively
if you want especifications you send me other e-mail
no problem
good BYE

Are you asking if this information is accurate or why did they do it that way?
I can only guess. It may be that this facilitates some interleaved addressing mode. I once saw where Apple swapped pins so their EROMs would not be interchangeable with the standard product.

Well, this is a very dumb question. Sorry for that.
I'm creating a circuit using the 27C160 EPROM memory in BYTE mode. The pin
Q15/A-1 has the function A-1 in the BYTE mode. I'm so sorry, but it means that
the memory is adressed A-1, A0, A1, A2 instead of A0, A1, A2...A-1????
Thanks Alexandre Souza
