Systems and methods for improving fuse systems in memory devices

A method, comprising:

• deriving a fuse data for one or more fuses in a plurality of fuses disposed in a fuse array of a memory device;
• transmitting the fuse data via a fuse array broadcasting system comprising an N-bit bus system to a first plurality of local fuse latches disposed outside of the fuse array;
• storing the fuse data at the first plurality of local fuse latches;
• and
• comparing the fuse data to determine if a redundant fuse included in the plurality of fuses should be activated by the memory device, wherein transmitting the fuse data comprises transmitting the fuse data via a token-based communication and wherein the broadcast clock signal is representative of a token clock signal.

A memory device, comprising:

• a memory bank accessible via a plurality of memory addresses;
• a fuse array comprising a plurality of fuses;
• a first plurality of local fuse latches disposed outside of the fuse array and configured to provide redundancy for the plurality of memory addresses;
• and
• a fuse array broadcasting system comprising an N-bit bus system, wherein the N-bit bus system is communicatively coupled to the fuse array and to the first plurality of local fuse latches, and wherein the fuse array broadcasting system is configured to communicate fuse data from the fuse array to the first plurality of local fuse latches via the N-bit bus system, wherein the N-bit bus system comprises a plurality of D-type flip flops coupled to a broadcast clock line and wherein the N-bit bus system is configured to use the plurality of D-type flip flops and a broadcast clock signal transmitted via the broadcast clock line to communicate the fuse data from the fuse array to the first plurality of local fuse latches via token-based communication.

A method, comprising:

• deriving a fuse data for one or more fuses in a plurality of fuses disposed in a fuse array of a memory device;
• transmitting the fuse data via a fuse array broadcasting system comprising an N-bit bus system to a first plurality of local fuse latches disposed outside of the fuse array;
• storing the fuse data at the first plurality of local fuse latches;
• comparing the fuse data to determine if a redundant fuse included in the plurality of fuses should be activated by the memory device;
• and
• transmitting testmode manual fuse data via the fuse array broadcasting system to the first plurality of local fuse latches, to a second plurality of local fuse latches disposed outside of the fuse array, to a third plurality of local fuse latches disposed outside of the fuse array, or to a combination thereof, wherein the second plurality of local fuse latches are configured to provide for reconfiguration of at least one circuit option for the memory device, and wherein the third plurality of fuse latches are configured to provide for test operations of one more circuitry of the memory device.
