  • Publication number: 20170123722
    Abstract: Systems and methods for managing transfer of data into and out of a host data buffer of a host are disclosed. In one implementation, a partial write completion module of a storage system retrieves from the host, stores in a memory, and acknowledges retrieving and storing with a partial write completion message, each subset of a larger set of data associated with a host write command. The host may utilize received partial write completion messages to release and use the portion of the host data buffer that had been storing the subset identified in the message rather than waiting to release data associated with the host write command until all the data associated with the command is stored in the memory. The memory in which each subset is stored may be non-volatile memory in the storage device or a shadow buffer on the host or an external memory device.

  • Publication number: 20160299814
    Abstract: A method for data storage includes storing data in a memory that includes one or more memory units, each memory unit including memory blocks. The stored data is compacted by copying at least a portion of the data from a first memory block to a second memory block, and subsequently erasing the first memory block. Upon detecting a failure in the second memory block after copying the portion of the data and before erasure of the first memory block, the portion of the data is recovered by reading the portion from the first memory block.

  • Patent number: 9405705
    Abstract: A data storage system includes a plurality of non-volatile memory devices arranged in one or more sets, a main controller and one or more processors. The main controller is configured to accept commands from a host and to convert the commands into recipes. Each recipe includes a list of multiple memory operations to be performed sequentially in the non-volatile memory devices belonging to one of the sets. Each of the processors is associated with a respective set of the non-volatile memory devices, and is configured to receive one or more of the recipes from the main controller and to execute the memory operations specified in the received recipes in the non-volatile memory devices belonging to the respective set.

  • Patent number: 9058288
    Abstract: A method for data storage includes storing two or more data items in a non-volatile memory. Redundancy information is calculated over the data items, and the redundancy information is stored in a volatile memory. Upon a failure to retrieve a data item from the non-volatile memory, the data item is reconstructed from remaining data items stored in the non-volatile memory and from the redundancy information stored in the volatile memory.

  • Patent number: 9043590
    Abstract: A memory device includes a plurality of memory cells, a token input interface, a token output interface and control circuitry. The control circuitry is configured to accept a storage command, to condition execution of at least a part of the storage command on a presence of a token pulse on the token input interface, to execute the storage command, including the conditioned part, in the memory cells upon reception of the token pulse on the token input interface, and to reproduce the token pulse on the token output interface upon completion of the execution.

  • Patent number: 8914670
    Abstract: A method includes, in a non-volatile memory that includes multiple memory blocks, defining a redundancy zone that includes at least an old parity block, a new parity block and multiple active blocks of which one block is defined as an open block. Data is stored in the redundancy zone and the stored data is protected, such that new input data is stored in the open block, redundancy information for the active blocks including the open block is stored in the new parity block, and the redundancy information for the active blocks excluding the open block is stored in the old parity block. Upon filling the open block and the new parity block, an alternative block is assigned to serve as the open block and the new parity block is assigned to serve as the old parity block.

  • Patent number: 8650465
    Abstract: A method for data storage includes encoding input data with an Error Correction Code (ECC), to produce encoded data. The encoded data is formatted in a super-frame consisting of a given number of burst sequences arranged in parallel, each burst sequence consisting of one or more bursts of multiple bytes of the encoded data. The burst sequences of the super-frame are stored in respective memory devices over a single data bus having a bus width, in bytes, that is equal to the given number.
