摘要： Integrated circuits with memory built-in self test (MBIST) circuitry and methods are disclosed that employ enhanced features. In one aspect of the invention, MBST circuitry is used set memory elements of arrays to a first state and then to an inverse state during a burn-in operation to maintain each of the two opposing states for a desired time in order to either force a failure of the integrated circuit component or produce a pre-stressed component beyond an infancy stage. Preferably, an integrated circuit is provided having MIBST circuitry configured to serially test multiple arrays of memory elements within a component of the integrated circuit and to also conduct parallel initialization of the serially tested arrays.
