  • Copyback optimization for memory system
    Patent number: 8572335
    Abstract: In a copyback or read operation for a non-volatile memory subsystem, data page change indicators are used to manage transfers of data pages between a register in non-volatile memory and a controller that is external to the non-volatile memory.
    Type: Grant

  • Power Event Indicator for Managed Memory Device
    Publication number: 20090249087
    Abstract: A host device coupled to a managed memory device (e.g., a managed NAND device) generates a signal indicative of an expected power event. The signal is received by the managed memory device which performs one or more operations in response to the signal. In some implementations, a pin is added to a power management chip that provides a signal to interrupt the managed memory device when a power event (e.g., power failure, system reset) is expected to occur. The signal provides the managed memory device time to finish one or more operations (e.g., the last physical operation) and to place the managed memory device in a known and/or safe state prior to the occurrence of the power event.
