Abstract :
A verification vehicle was implemented in parallel with process development to accelerate memory and product introduction. 320 Kb of SRAM, DRAM, and ROM were integrated using architectural and circuit techniques supporting rapid analysis of manufacturability and characterization of memory-specific parasitics. It is shown that the BIST (built-in self-test) circuitry is well-suited to providing vital information on manufacturing defects and yield in minimal test time. The novel parasitic characterization circuitry permits measurements which serve to greatly improve the simulation accuracy of the final memory designs, allowing product deployment to take place less than one year after initial test chip access
