Either someone
at Hynix has a sense of humour, or they have run right
out of IC codes and have come full circle to 2708 again.
Several years ago, Motorola/IBM used the part number "7400" for some of their
PowerPC chips.
And of course a 4040 from Intel is a 4-bit microprocessor, from RCA it's
a 12 bit CMOS counter. I can never rememebr what the 4004 is in the
4000-eries CMOS, it's sufficiently rare that none of the data books I
have to hand list it.
