Abstract
An electronic circuit includes first and second circuits that include corresponding built-in-self-test (BIST) engines to perform memory testing operations on corresponding first and second memory block and generate first and second memory repair data. A multiplexer receives the first and second memory repair data and selectively transmits the first memory repair data during a first test cycle and the second memory repair data during a second test cycle. A shadow register buffers the first memory repair data during the first test cycle and a fuse processor sequentially receives and stores the first and second memory repair data during the second test cycle.
