Once a data storage device failure is detected, data redundancy is restored on the reserve storage space. The scan chain control sequentially closes the pass gates to separately test the components in the semiconductor test structure. The pool select logic selects a free buffer in the shared pool upon detecting no free buffer in the reserved pool.
