March algorithm for MBIST testing

Can some body tell why in march algorithm for MBIST we do read and write in ascending order and decending order. What is the significance of it?
Can some body suggest good books on this topic. which concentrates mainly on basics.

The MBIST algorithm to used is technology and IPs providers dependants who know how the bit cells are organised in their memories.
The MBIST algorithm type and order need to be provided by the IPs providers.

Hi rca,

I want to understand what faults it trying to target by reading/writing in ascending order and decending order or which faults we can't detect if we do just reading/writing in either ascending/decending order.

I hope you understand my question.

can you please suggest a link or book where each step of march algorithm is explained and which faults it is detecting in each step.


Thanks
Srikanth
