  • Publication number: 20200319970
    Abstract: Techniques are described for memory writes and reads according to a chip-kill scheme that allows recovery of multiple failed wordlines. In an example, when reading data from a superblock of the memory, where the decoding of multiple wordlines failed, a computer system schedules the decoding of failed wordlines based on quantity of bit errors and updates soft information based on convergence or divergence of the scheduled decoding. Such a computer system significantly reduces decoding failures associated with data reads from the memory and allows improved data retention in the memory.

  • Patent number: 10714195
    Abstract: A system includes memory cells arranged in blocks and a memory controller. The memory controller receives a read command to read a first block. The first block can be associated with a first read count and a first read threshold. The first read count is incremented when the first block is read, and when the first read count reaches the read threshold, a read reclaim test is performed. The first read count is set to zero after a power off or a read reclaim operation. When the first read count is zero, an adaptive read threshold is selected based on the number of bit errors. Further, in a read reclaim test, the number of bit errors is tested against an adaptive error threshold to determine whether a garbage collection operation is performed.

  • Patent number: 10707899
    Abstract: Techniques are described for performing a bit-flipping decoding scheme on a G-LDPC codeword. In an example, a decoding system uses two syndrome tables. The first syndrome table identifies a predefined syndrome for a component codeword that protects a bit of the G-LDPC codeword. This predefined syndrome is identified based on a location of the bit and is used to update a current syndrome of the component codeword. The second syndrome table identifies one or more bit error locations for the component codeword. The bit error locations are identified from the second syndrome table based on the current syndrome of the component codeword, as updated. In an example, the error locations are used to update a reliability of the bit if its location corresponds to one of the error locations. A bit flipping decision is made for the bit based on its reliability.
