Concurrent BISR: Revolutionizing Memory Repair in Modern Electronics

Concurrent BISR (Built-In Self-Repair) chains refer to a methodology that enables the simultaneous processing of multiple BISR chains during power-up, thereby facilitating faster loading of repair data. This approach allows for parallel processing of BISR chains, which can include a mix of compressed and uncompressed chains. The primary advantage of concurrent BISR chains is that they accelerate the loading of repair data during power-up, which can be particularly beneficial in systems where time-to-operation is critical. It’s worth noting that this feature is specifically utilized during the functional mode of circuit operation and is not applicable in manufacturing modes.

To implement concurrent BISR chains, the on-chip repair storage interface must incorpo
