Just the European Union, these droplets are legally prohibited to use for the sake of maintainability, they say it's not fuckin' to pollute the environment with failed circuit boards when they can be repaired. But now they are successfully replaced by BGA hulls. And the price of some simple standard microcontroller has now fallen many times, some Chinese or Korean (abov for example) clone 8051 μ worth mere pennies. About the fact that the Chinese clone stm32f103c8t6 with additional nittyaks in the form of a built-in CAN costs 0.3 bucks, or ESP32 with WiFi at a price-quality does everyone - I do not say at all.
The USSR...maybe theoretically could, here I am not sure, but historically our factories were so formed that, as I wrote above, prevents such execution. The Japanese see the same thing.
The Soviet Union was able to do this in all sorts of hours of electronics, since it is not particularly difficult. But about flash memory or EEPROM in general, I did not see anything like this in Soviet radio magazines, nor in the 90s - in the already almost dead post-Soviet domestic electronics, the coolest thing that could be used is a puppy with ultraviolet erasure and dynamic memory K565RU5 some.
