Method and apparatus for initializing an integrated circuit using compressed data from a remote fusebox

A method for initializing an integrated circuit, said method comprising the steps of:

• reading compressed control data from a fuse matrix located within said integrated circuit;
• decoding said compressed control data to produce decompressed control data;
• and
• latching said decompressed control data to control functional circuit elements, wherein said integrated circuit is an integrated circuit within a multi-chip module, and wherein said method further comprises the step of selecting said integrated circuit to receive said decompressed control data, and wherein said step of latching is performed responsive to said step of selecting.

An integrated circuit, comprising:

• a fusebox containing a plurality of fuses;
• a decompresser coupled to said fusebox for reading values from said fuses and decompressing said values to produce control data;
• a plurality of latches coupled to said decompressor for latching said control data to control said functional logic;
• and
• a power-on-reset circuitry coupled to said decompressor for indicating initialization of said integrated circuit, wherein said decompressor decompresses said values in response to said indication.

A multi-chip module comprising:

• a plurality of dies;
• a fusebox coupled to each of said plurality of dies, wherein said fusebox contains a plurality of fuses;
• a decompressor for reading values from said plurality of fuses and decompressing said values to produce control data;
• and
• a plurality of latches within each of said plurality of dies, wherein said plurality of latches is coupled to said decompressor, and wherein said latches hold said control data to control said functional logic.
