Talk:Programmable Array Logic

The first PALs

I reverted 209.78.18.231 (talk · contribs)'s edits because they are possibly wrong and his other edits are POVed and possibly sneaky vandalism. The one source I found said that MMI had the first not IBM. However, I don't know enough of the topic to make clear call either way. --metta, The Sunborn 19:32, 21 May 2005 (UTC)[reply]

Yes, you don't know enough about the topic. First: IBM but not for sale to the public, Second: Signetics FPLA's, Third: MMI PAL's(tm)

MMI PAL patent, enjoy: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=/netahtml/srchnum.htm&r=1&f=G&l=50&s1=4,124,899.WKU.&OS=PN/4,124,899&RS=PN/4,124,899

AND and OR

How come AND and OR gates are so fundamental to PALs and other electronical structures, as it is mentioned in this article? Thanks, Abdull

It's a Logic Array as opposed to a Memory Array. AND and OR is logic. IBM invented them and has the first patents.
