摘要: A serial memory interface includes a register having a plurality of flip-flops forming a scan chain and coupled to both the input and output terminals of memory cells. An interlaced scan is established by interconnecting scan chains between multiple memory blocks. The interface structure provides a means for efficiently performing a built-in self test of an embedded memory while requiring minimal overhead in hardware structure.
