Abstract: Apparatuses, systems, methods, and computer program products are disclosed for reducing routing signals. An apparatus includes a first block decoder circuit that senses bad block data of a first latch circuit corresponding to a first memory block and couple the bad block data onto a bus. An apparatus includes a comparator circuit that compares the bad block data against a reference, sets a bad block flag, and routes the bad block flag on a routing line across an array of storage elements. An apparatus includes a second block decoder circuit that receives the bad block flag from the routing line, determines a condition of the first memory block based on the bad block flag, and determines a generation of a block selection signal for selecting a second memory block.
