  • Publication number: 20100332177
    Abstract: A test access control apparatus includes test access mechanism (TAM) buses and an extended IEEE 1149.1 Test Access Port (TAP) Controller. The TAM buses support memory built-in-self-test (BIST) circuit for the memory known-good-die (KGD) test, scan chains for the logic KGD test; and through-silicon-via (TSV) chains that are configured to conduct the TSV test that verifies any defect in vertical interconnects between any two chip layers of the stacked chip device. The TAP Controller is coupled to the TAM buses and is configured to control the memory KGD test, the logic KGD test and the TSV test between two chip layers. A cost-effective connection or configuration of test access control apparatus in 3D-IC is also present.

  • Publication number: 20100281341
    Abstract: A management method for a non-volatile memory comprises the steps of providing the non-volatile memory with at least one block having a plurality of pages to store user data and parity data; dividing at least one of the pages into a plurality of partitions each including the user data and parity data; determining codeword length of each of the partitions, the codeword length comprising message length with sufficient storage to store the user data and parity length storing the parity data; and storing extra parity data in the partition with the codeword length. When storing extra parity data in the codeword length, the parity length is increased and the message length is decreased.
