Biometric monitoring devices, including various technologies that may be implemented in such devices, are discussed herein. Also provided is a hydrophilic pledget for applying the liquid to an area which is to be treated, and a structure for maintaining the hydrophilic pledget in a position opposite to the outlet for the evacuation of the liquid from the cartridge. Routing circuitry, such as mux circuitry, in the block repair device is configured by the stored block repair configuration to output some row and column address bits from received row and column addresses in a selected ratio.
