In the early 80’s, MOSTEK was the largest memory manufacturer in the world.

I found a shelf of MOSTEK mementos on my parents’ bookshelf, as my Dad ran the MOSTEK DRAM fab… and it brought back memories of my childhood.

I inserted banks of chips like the predecessor to this one into my Apple ][ to upgrade it from 16k to 48K.

At work, my Dad took me on fab tours of magical halls filled with exotic equipment and machines of all types, with a massive network of pipes feeding them. It was like the Hogwarts in a clean room, and I wanted to work there.

But I was only 17, and they had a strict policy against hiring anyone under 18. No way to do it, said Dad. So I went to work for a temp agency that summer. On the first day, they asked me if I would like to work at… MOSTEK. My eyes popped. The back door! Literally, in a way, as I worked in the “back end” of the fab, where we did final quality control tests on fully packaged chips (like the one above, but encased in black plastic instead of clear). After a few days on the job, proudly sporting my company badge, I strolled into his office to surprise him with my presence.

From my earliest memories, my father instilled a sense of scientific curiosity in me, and a love of learning about technology. He would often ask me how things work, from tape recorders to rainbows, and talk through a logical decomposition, invoking physics instead of fairies.

On this Thanksgiving, I want to give a special thanks to my father.

  1. The white arrows mark the very first 256K DRAM that passed wafer-probe testing:
    First prime good 256K dieAnd it happened on my birthday no less. =)
    But it was late to market, with advanced features for future scalability and two-layer metal. The Japanese entry into the memory business collapsed prices. I recall the detail that in 1985, they were selling chips for 25 cents that cost MOSTEK $1 to produce. The late ramp of this 256K product generation led to the collapse of MOSTEK’s business, massive layoffs, and our move to California.

  2. The early years:early chips
    • MK 4006 = 1k PMOS aluminum-gate DRAM
    • MK 6010 = Single chip calculator (like the Intel 4004)
    • MK 4096 = 4096 X 1 bit DRAM, with the novelty of address multiplexing for future scaling
    • MK 4027 = silicon-gate version of the 4kb DRAM
    • MK 4116 = 16kb double-poly silicon-gate DRAM
    • MK 3870 = single chip version of the Fairchild F8 (8-bit processor)
    • MK 36000 = 64Kb masked ROM (8k x 8)
    • MK 5116 = the first single-chip CMOS voice CODEC
    • MK 4801 = SRAM with Poly 5, the first fully implanted manufacturing process

  3. Wow. We competed – I was at inmos from 1982-1989. But not doing DRAMs, that mainly came out of Colorado Springs.

  4. 🙂
    yup… yer dad … he’s da man!

  5. Nice story about your Dad….
    The tech part is gibberish to me.

  6. Your dad seems fantastic and great that he taught you so many wonderful things… so you can be thankful to your dad and also to Japanese for playing this strange role in your life… it reminds me this taoist "maybe" story about good and bad luck..

    and interesting history on MOSTEK memories… for me 64 (1264) number brings some memories of Intel’s fab… and clean room…

  7. Great personal story Steve. I can only imagine that your father is as proud of you as you are of him. May that tradition continue for you as well.

  8. Reminds me of the stories told by Richard Feynman about his dad. Dad didn’t just answer his son’s questions. He would explain the answers and get his son to think about how and why the answers came about. His son became involved in the discussion and learned to use his own knowledge and insight to think on his own. Parent, mentor, and role model all wrapped into one dad or mom. Every child should have one or two.

  9. It would be great to see a photo of you and your Dad together. You must be as proud of him as he is of you.. 🙂 🙂

  10. Nice. I had two commodore 8-bit computers.

  11. Thanks y’all.

    LesMeister: yes! Here’s one that had us abuzz.

    Another memory from Thanksgiving dinner talk last night: MOSTEK also had an x86 license from Intel, which could have gone so many different directions. Don Estridge, who ran IBM’s PC group in Boca Raton, was on his way to visit MOSTEK in August 1985 to negotiate when Delta flight 191 hit the highway rather than the runway at DFW. Who knows what could have been.

  12. Hmmm…A Luddite gets an education here.
    I found a good article reviewing the history of IBM’s "portable computers" and the like here;

  13. Yep, dads can be thanked for many things, especially for curiosity and sense of humor:) and some genetic facial features:)

  14. I live near the Mostek plant in Carrollton. 55 acres and an amazing assortment of buildings that now sit empty. It is on the tax rolls for 24 million and will probably sell at a bargain price. 1200 people worked there just a short time ago.

  15. We used to have a couple of tech jobbies here too….what were they called ?
    Oh ya;
    JDS Uniphase and Nortel……Mitel…Corel

  16. Oh, i see you are giving cutting edge tech talks to Britney Spears fans:

    theventurebrothers.4ql.net/the-venture-brothers-season-2/…

    SJ and BS in one sentence… – very very funny:) i will show it to my daughter:)

  17. Hi Steve.. Thank you for the link to the photo of you and your Dad with Buzz Aldrin..!!
    That really is special..
    I see you have one with Neil Armstrong too..!!
    All you need now is one with Michael Collins to complete the trio..:):)
    Have a great Christmas..!!

  18. Oh, and some memories from the former Motorola fab in Arizona, when I found myself there again in 2008:

    Déjà vu

  19. I worked at Mostek from the Summer of 1978 till the summer of 1989…ran the Process R&D Analytical lab (SEM, TEM and other stuff). It was a great place to work in the early days. There were several Fabs that turned out DRAMS….I got there just as they were bringing up Fab 4 and then Fab 5 was added, the had Fabs 1, 2 and 3 before I came….they added Fab 6 in later years. The good years to work at Mostek were the early years…UTC and SGS-Thomson made it not such a fun place to work in general. The process R&D Group had some very sharp people though.
