Any links to working ASICs (N-Factor: 10; N: 2048)?
KNC Titan can mine Garlicoin and any scrypt-n coin with an n up to 19. It's a released miner that had went onto production. Units of it are still sold second hand. Very powerful one, mind you.
https://github.com/KnCMiner/knc-asic/blob/d83f1e67785eff0af00175d85564ace840c28186/knc-asic.h#L10After further investigation, Bitmain's the most reputable manufacturer, L1 miner seems to be capable of mining scrypt-n. Read below:
Our brand new, high-performance L1 will be hashing at 120MH/s with the market-best pricing of only $599.00 USD per unit with free shipping worldwide, hailing in at a market-topping rate $5/MH/s. This ensures our L1 will be absolute the best $/MH/s as well as power efficiency spec in the Scrypt mining market. Whats more, a dramatic discount will be given to bulk orders.
L1 will be produced with our state-of-art chip powered by the 28nm tech process. The efficiency is only 2.37J/MH at Core Voltage 0.81v on chip level. The Core Voltage and Hash Rate will be adjustable by software, over clocking and under clocking will be very easy to operate while miners trade-off the speed and efficiency. Moreover, the miner will be able to mine multifarious scrypt based altcoin, of which scrypt length can be 1024, 2048, 4096 (n = 10, 11 or 12).
The above miners are confirmed to have been released and both able to mine Garlicoin. Scrypt-n is certainly ASIC broken, miners that can mine Garlicoin exist already too and more could be created as well.
There are other SCRYPT-N ASICs that were advertised but I don't have confirmation about their releases (all listed below). A user in this thread talked about the following having been released:

Didn't Vertcoin switch from that algo for that very reason? Because ASICs for it were hitting the market. They were rendered useless pretty quickly though.
May be dev team have a lot of this ASIC so they choose this algo. In fact this ASICs was created by only one Estonian/Russian company some years ago and now you cant buy this new ASIC. I have bouhgt in Moscow 6 used Tritons fo $80-110 each. Each give 5-12 Mh/s (suppose some chips already broken) in Scrypt-N.
More over,
http://blissdevices.com/ and
https://www.flowertechnology.com/have been talked about by different companies but most seem to have vanished after vertcoin and its forked switched algos back in the day so I can't vouch for their validity as there aren't enough records.
There's also a company that has a working prototype and upcoming releases
https://www.youtube.com/watch?v=OYuv93BHqu0BITMAIN Antminer L1 - CANCELLED production, preorders got refunded. This is not "confirmed to have been released".
"hashcoins ASICs" - preorders was in 2014, possibly not shipped.
Looks like KNC Titan is only viable existing option. We see variables in code. Benchmarks would be great.
I couldn't find if it actually would work and how well it would perform, compared to modern GPU (you can't get same hashrate for scrypt and scrypt-N).
