    摘要: Defect management logic extends a useful life of a memory system. For example, as discussed herein, failure detection logic detects occurrence of a failure in a memory system. Defect management logic determines a type of the failure such as whether the failure is an infant mortality type failure or a late-life type of failure. Depending on the type of failure, the defect management logic performs different operations to extend the useful life of the memory system. For example, for early life failures, the defect management logic can retire a portion of the block including the failure. For late life failures, due to excessive reads/writes, the defect management logic can convert the failing block from operating in a first bit-per-cell storage density mode to operating in a second bit-per-cell storage density mode.

    摘要: A memory device may include two or more memory cells in an integrated circuit, at least one flash cell acting as a select gate coupled to the two or more memory cells, and an interface to accept a select gate erase command and a select gate program command during normal operation of the integrated circuit. The integrated circuit may be capable to perform operations to erase the at least one select gate in response to the select gate erase command, and program the at least one select gate in response to the select gate program command.

    摘要: Methods and apparatus to provide dynamic window to improve NAND (Not And) memory endurance are described. In one embodiment, a program-erase window associated with a NAND memory device is dynamically varied by starting with a higher erase verify (TEV) voltage and lowering the TEV voltage with subsequent cycles over a life of the NAND memory device based on a current cycle count value. Alternatively, the program-erase window is dynamically varied by starting with a higher erase verify (PV) voltage and erase verify (TEV) voltage and lowering the PV and TEV voltages with subsequent cycles over a life of the NAND memory device based on the current cycle count value. Other embodiments are also disclosed and claimed.
