Patent ID: 7237163

Claim:
A system, comprising: a plurality of latches; a plurality of first multiplexers (muxes) coupled to the plurality of latches; wherein each latch of the plurality of latches is uniquely coupled to a corresponding first mux; wherein each first mux is configured to receive a first select signal, a data input, and a first scan input, and to transmit to the corresponding latch either the data input or the first scan input based on the first select signal; a plurality of second muxes coupled to the plurality of first muxes; wherein each second mux is uniquely coupled to a corresponding first mux; wherein each second mux is configured to receive a second select signal, a second scan input, and a low leakage vector (LLV) input, and to transmit to the corresponding first mux either the second scan input or the LLV input based on the second select signal; and wherein the LLV input is configured to reduce a leakage current associated with the plurality of latches.
