DRAM in the 80's was a scarce commodity in the US,
when the
government imposed anti-dumping penalties on the big Asian makers.
It was pretty ugly; there were even some break-ins in Silicon Valley
for the sole purpose of stealing DRAM.
In the mid 1990's oer here there were what became known as 'SIMM
thieves'. Burglars who broke into companies and stole, not the complete
PCs, but the RAM SIMMs from them. At the time I was working at Cambridge
University Engineering Department, and that got targeted a couple of times.
