Abstract: A method in a storage device includes receiving from a host storage commands for execution in a non-volatile memory of the storage device. At least a subset of the storage commands are to be executed in accordance with an order-of-arrival in which the storage commands in the subset are received. The received storage commands are executed in the non-volatile memory in accordance with internal scheduling criteria of the storage device, which permit deviations from the order-of-arrival, but such that execution of the storage commands in the subset reflects the order-of-arrival to the host.

Abstract: A method for data storage includes providing a mapping of data pages to physical pages, in which each physical page holds a non-integer number of the data pages, for storage of data in at least one memory block, including a plurality of the physical pages, in a memory device. The data pages that are mapped to the memory block are partitioned into groups, such that failure of any memory unit, which consists of a predefined number of the physical pages in the memory device, will produce errors in no more than one data page in each group. The data pages is stored in the physical pages of the memory block in accordance with the mapping, while a redundant storage scheme is applied among the data pages of each group.

Abstract: A method includes executing a first memory access operation in a memory. A progress indication, which is indicative of a progress of execution of the first memory access operation, is obtained from the memory. Based on the progress indication, a decision is made whether to suspend the execution of the first memory access operation in order to execute a second memory access operation.

Abstract: A method includes storing data encoded with an Error Correction Code (ECC) in analog memory cells, by buffering the data in a volatile buffer and then writing the buffered data to the analog memory cells while overwriting at least some of the data in the volatile buffer with success indications. Upon detecting a failure in writing the buffered data to the analog memory cells, recovered data is produced by reading both the volatile buffer and the analog memory cells, assigning reliability metrics to respective bits of the recovered data depending on whether the bits were read from the volatile buffer or from the analog memory cells, and applying ECC decoding to the recovered data using the reliability metrics. The recovered data is re-programmed.

Abstract: A method for data storage includes defining an end-to-end mapping between data bits to be stored in a memory device that includes multiple memory cells and predefined programming levels. The data bits are mapped into mapped bits, so that the number of the mapped bits is smaller than the number of the data bits. The data bits are stored in the memory device by programming the mapped bits in the memory cells using a programming scheme that guarantees the end-to-end mapping. After storing the data bits, the data bits are read from the memory device in accordance with the end-to-end mapping.

Abstract: A system for data storage includes one or more non-volatile memory (NVM) devices, each device including multiple memory blocks, and a processor. The processor is configured to assign the memory blocks into groups, to apply a redundant data storage scheme in each of the groups, to identify a group of the memory blocks including at least one bad block that renders remaining memory blocks in the group orphan blocks, to select a type of data suitable for storage in the orphan blocks, and to store the data of the identified type in the orphan blocks.

Abstract: A method includes, in a host that stores data in a storage device, detecting an event that is indicative, statistically and not deterministically, of an imminent power shutdown in the host. A notification is sent to the storage device responsively to the detected event, so as to cause the storage device to initiate preparatory action for the imminent power shutdown.
