  • Nonvolatile memory with modulated error correction coding
    Patent number: 8001441
    Abstract: Data is stored in a nonvolatile memory so that different pages of data stored in the same memory cells are encoded according to different encoding schemes. A first page is decoded according to its encoding scheme and an output is provided based on the decoding of the first page that is subsequently used in decoding a second page.
    Type: Grant

  • Methods of varying read threshold voltage in nonvolatile memory
    Patent number: 7904788
    Abstract: Data is read from a nonvolatile memory array using one or more read voltages that are adjusted during memory life. Programming target voltages and read voltages may be adjusted together over memory life to map memory states to an increasingly wide threshold window. Individual memory states are mapped to sub-ranges that are made wider, reducing errors.

  • Soft-input soft-output decoder for nonvolatile memory
    Patent number: 7904783
    Abstract: In a nonvolatile memory system, data is read from a memory array and used to obtain likelihood values, which are then provided to a soft-input soft-output decoder. The soft-input soft-output decoder calculates output likelihood values from input likelihood values and from parity data that was previously added according to an encoding scheme.

  • Methods of adapting operation of nonvolatile memory
    Patent number: 7805663
    Abstract: In a nonvolatile memory system a Soft-Input Soft-Output (SISO) decoder corrects errors in data that is read from a memory and a statistical unit connected to the SISO decoder collects data regarding corrections. The statistical unit generates at least one output based on the collected data and at least one operating parameter of the memory is modified in response to the output.

  • Fax overflow system
    Patent number: 5881136
    Abstract: In a system where fax messages are directed to a store and forward system when a fax machine is busy: When fax messages are stored and an attempt is made to re-deliver the message, an ID related to the serial number of the storage system is placed in the fax header. When a message is received by the store and forward system, the header is interrogated and if an ID related to the serial number of the receiving machine is detected, the fax is not again stored and the system notes that the transmission to the fax machine was not successful.
