Abstract:
A circuit includes a multipath memory having multiple cells and a plurality of sequence generators. Each sequence generator of the plurality of sequence generators drives one separate cell of the multiple cells via an automatic test pattern generator (ATPG) mode signal for each cell. The ATPG mode signal for each cell is configured via a sequence configuration input that controls a timing sequence to test each cell. The state of the ATPG mode signal of each cell selects whether test data or functional data is output from the respective cell.
