    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, applying ECC decoding to the recovered data using the reliability metrics and reprogramming the recovered data.

    Abstract: A method includes communicating over an interface between a controller and multiple memory dies, which comprise respective on-die terminations (ODTs) that are each connectable to the interface by the controller. A plurality of termination settings are evaluated, each termination setting specifies a respective subset of the ODTs to be connected to the interface, so as to identify a preferred termination setting in which the communication quality with a given memory die meets a predefined criterion. Subsequent communication with the given memory die is performed while applying the preferred termination setting.

    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.

    Abstract: A method includes, in a memory including analog memory cells, storing first data in a group of the memory cells using a first type of storage command that writes respective analog values to the memory cells in the group. Second data is stored in the memory cells in the group, in addition to the first data, using a second type of storage command that modifies the respective analog values of the memory cells in the group. Upon detecting imminent interruption of electrical power to the memory during storage of the second data, a switch is made to perform an alternative storage operation that is faster than the second type of storage command and protects at least the first data from the interruption.

    Abstract: A method for data storage includes generating a first scrambling sequence and a second scrambling sequence that is different from the first scrambling sequence. A combined sequence, which is equal to a bit-wise XOR between the first and second scrambling sequences, is generated. Data is copied from a first location in a memory in which the data is scrambled using the first scrambling sequence, to a second location in the memory in which the data is to be scrambled using the second scrambling sequence, by reading the data from the first location, scrambling the read data using the combined sequence, and then storing the data in the second location.
