So, the chip is fake, but how come such chips could work satisfactorily in their place in a PC??

It wouldn't.

I don't think 8 byte RAM chip is used in any computer. You'd need 128 of these to get one kilobyte of RAM!

  Some historical background: The 8 byte RAM chips were used in minicomputers in the 1970s to implement CPU registers, for example in the Xerox Alto. The advantage of TTL was that it was much faster than MOS memory.

This is downvoted, but actually a legitimate question. Often, counterfeits do work, but just don't match the specifications with respect to voltage rating, durability, etc.

  Yes, a totally non-working fake isn't the most common thing to occur. Unless they got the counterfeits for free, the vendor is losing money on replacing the fakes with real ones. They are assuming everyone will either never use the chip or just assume they fried the chip and buy another. Selling rejects from the fab or clones as legit is much easier to get away with.

Theory: this particular chip is obscure, and the very few who would buy it are either (1) collectors who never intended to use it, or (2) people stockpiling hard-to-find parts for legacy hardware. Either buyer won't discover that the chip is fake until the seller has long-ago skipped town. Indeed, Ken was in group #1 (collector) but a very unusual kind who then proceeded to tear down the chip.

If we are talking about this article, then: 1. this chip supposed to be old era memory chip (64bit of data -> 8 bytes) it wouldn't work on your PC 2. It was DTMF chip not memory chip, so it couldn't work at all as a memory chip I guess the idea was that it costed $1, the seller shipped it, the chip would never work, but cost of shipping it back would be greater, so you would just eat the cost and move on. As with other kinds of fakes, they try to emulate the functionality, and often work, some even surprisingly better than expected, but they are always worse than originals. So either you won't get performance that's mentioned in the spec, or it break sooner or has some other issues that get apparent once you start using it.
