摘要： A method includes receiving one or more storage commands and at least one flush command in a storage device, which includes a non-volatile memory and a volatile buffer for buffering data received for storage in the non-volatile memory. The flush command instructs the storage device to commit the data buffered in the volatile buffer to the non-volatile memory. The storage commands are executed in accordance with a first storage rule. The flush command is executed in accordance with a second storage rule having smaller latency relative to the first storage rule.

摘要： A method for data storage includes receiving a plurality of data items for storage in a memory, including at least first data items that are associated with a first data source and second data items that are associated with a second data source, such that the first and second data items are interleaved with one another over time. The first data items are de-interleaved from the second data items, by identifying a respective data source with which each received data item is associated. The de-interleaved first data items and the de-interleaved second data items are stored in the memory.

摘要： A method for data storage includes storing data in a group of analog memory cells by writing into the memory cells in the group respective storage values, which program each of the analog memory cells to a respective programming state selected from a predefined set of programming states, including at least first and second programming states, which are applied respectively to first and second subsets of the memory cells, whereby the storage values held in the memory cells in the first and second subsets are distributed in accordance with respective first and second distributions. A first median of the first distribution is estimated, and a read threshold, which differentiates between the first and second programming states, is calculated based on the estimated first median. The data is retrieved from the analog memory cells in the group by reading the storage values using the calculated read threshold.

摘要： A data storage method includes identifying, in a set of data items associated with respective logical addresses for storage in a memory, a first subset of the logical addresses associated with the data items containing application data, and a second subset of the logical addresses associated with the data items containing parity information that has been calculated over the application data. The data items associated with the first identified subset are stored in one or more first physical memory areas of the memory, and the data items associated with the second identified subset are stored in one or more second physical memory areas of the memory, different from the first physical memory areas. A memory management task is performed independently in the first physical memory areas and in the second physical memory areas.

摘要： A method for data storage includes predefining an order of programming a plurality of analog memory cells that are arranged in rows. The order specifies that for a given row having neighboring rows on first and second sides, the memory cells in the given row are programmed only while the memory cells in the neighboring rows on at least one of the sides are in an erased state, and that the memory cells in the given row are programmed to assume a highest programming level, which corresponds to a largest analog value among the programming levels of the cells, only after programming all the memory cells in the given row to assume the programming levels other than the highest level. Data is stored in the memory cells by programming the memory cells in accordance with the predefined order.

摘要： 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.
