摘要

This paper proposes an enhanced IEEE 1500 test wrapper to support the testing and diagnosis of the single-port or multi-port RAM core attached to the enhanced IEEE 1500 test wrapper without incurring large area overhead to small memories. Effective test time reduction techniques for the proposed test scheme are also proposed. Simulation results show that the additional area cost for implementing the enhanced IEEE 1500 test wrapper is only about 0.58% for a 64 K-bit single-port RAM and only 0.57% for a 64 K-bit two-port RAM in 90-nm technology.
