Förlag: IEEE--Institute of Electrical and Electronics Engineers Inc.
Embedded First-InFirst-Out (FIFO) memories are increasingly used in many IC designs.We have created a new full-custom embedded FIFO module withasynchronous read and write clocks, which is at least a factor twosmaller and also faster than SRAM-based and standard-cell-basedcounterparts. The detection qualities of the FIFO test for bothhard and weak resistive shorts and opens have been analyzed by anIFA-like method based on analog simulation. The defect coverage ofthe initial FIFO test for shorts in the bit-cell matrix has beenimproved by inclusion of an additional data background andlow-voltage testing; for low-resistant shorts, 100% defect coverageis obtained. The defect coverage for opens has been improved by anew test procedure which includes waitingperiods.
