Classification: CPC H  G | IPC G  H

Claim 1:
2. The integrated circuit of claim 1, wherein the decision circuit comprises:
a data compression circuit, for compressing the user configuration data content having X bits to generate the user configuration key content having Y bits smaller than X bits;
a comparator circuit, coupled to the data compression circuit, for comparing the user configuration key content having Y bits with the key data content having Y bits to generate a comparison signal; and
a multiplexer, coupled to the programmable memory circuit and the comparator circuit, for:
selecting the fallback configuration data content having X bits as the output data of the decision circuit when the comparison signal indicates that the user configuration key content does not match the key data content; and
selecting the user configuration data content having X bits as the output data when the comparison signal indicates that the user configuration key content matches the key data content.
