I just wanted to make sure there are not generic of a ASIC chip. In regular computers, each PC manufacturer does not have their own chip, you have generic Intel I7 or AMD Ryzen chip that any person or company can purchase.
Intel and AMD are NOT "generic" - they just happen to be widely-available competing product lines with VERY similar capabilities and an overlapping range of performance.
At least one of the ASIC miner chip houses (BW.com I think) uses Global Foundries as opposed to the more common usage of TSMC to make the actual chips.
The foundries don't DESIGN the chips, they just make them to specification on contract terms (as they do for AMD and IBM and NVidia and Apple among MANY others - Samsung and Intel have their OWN foundries).
The DESIGN of the chip is owned by the company that designed it.
