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 receiving in a memory device data for storage in a group of memory cells. The data is stored in the group by performing a Program and Verify (P&V) process, which applies to the memory cells in the group a sequence of programming pulses and compares respective analog values of the memory cells in the group to respective verification thresholds. Immediately following successful completion of the P&V process, a mismatch between the stored data and the received data is detected in the memory device. An error in storage of the data is reported responsively to the mismatch.

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 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 for data storage, includes holding a definition of a speculative readout mode for readout in a storage device, in which the storage device is requested to read a data unit having a data unit size, and in response the storage device retrieves a storage page that contains the data unit and has a storage page size larger than the data unit size, and retains the storage page in preparation for subsequent requests. Activation of the speculative readout mode is coordinated. A readout command using the speculative readout mode is performed.

Abstract: An integrated circuit includes fuse readout logic and first and second sets of fuses. One of the sets includes one or more primary fuses whose burn states represent respective bit values, and the other of the sets includes one or more secondary fuses whose burn states are indicative of the bit values stored in the primary fuses. The fuse readout logic is configured to read the bit values by sensing the burn states of the primary fuses, and to conditionally correct the read bit values by sensing the burn states of one or more of the secondary fuses.
