Abstract: A method for data storage includes assigning in a memory that includes one or more storage devices a first storage area for storage of user data, and a second storage area, which is separate from the first storage area, for storage of redundancy information related to the user data. Input data is processed to produce redundancy data, and the input data is stored in the first storage area using at least one first write command. The redundancy data is stored in the second storage area using at least one second write command, separate from the first write command.

Abstract: A method for data storage includes receiving in a memory device data for storage in a group of analog 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 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.

Abstract: A method for data storage includes, in a system that includes a host having a host memory and a memory controller that is separate from the host and stores data for the host in a non-volatile memory including multiple analog memory cells, storing in the host memory information items relating to respective groups of the analog memory cells of the non-volatile memory. A command that causes the memory controller to access a given group of the analog memory cells is received from the host. In response to the command, a respective information item relating to the given group of the analog memory cells is retrieved from the host memory by the memory controller, and the given group of the analog memory cells is accessed using the retrieved information item.

Abstract: An apparatus includes an interface and a processor. The interface is configured to communicate with multiple memory devices over a bus that includes a plurality of parallel data lines. The processor is configured to request the memory devices to provide respective status reports, and to receive the status reports from the memory devices such that, in a given clock cycle of the bus, the multiple status reports from the respective memory devices are received in parallel over respective different subsets of the data lines of the bus.

Abstract: A method for data storage in a memory that includes multiple analog memory cells fabricated using respective physical media, includes identifying a group of the memory cells whose physical media have deteriorated over time below a given storage quality level. A rejuvenation process, which causes the physical media of the memory cells in the group to meet the given storage quality level, is applied to the identified group. Data is stored in the rejuvenated group of the memory cells.

Abstract: In a system that includes a host and a memory controller that is separate from the host and stores data for the host in a non-volatile memory, a method for data storage includes transferring from the memory controller to the host one or more source blocks from the non-volatile memory for compaction. The source blocks are compacted in the host by copying valid data from the source blocks into one or more destination blocks. The destination blocks are transferred from the host to the memory controller, and the destination blocks are stored by the memory controller in the non-volatile memory.

Abstract: A method for data storage in a non-volatile memory includes storing data in the non-volatile memory using a first storage configuration while the non-volatile memory is supplied with electrical power. After storing the data, an indication is accepted, indicating that shut-off of the electrical power is imminent. Responsively to the indication and before the shut-off, at least some of the data is re-programmed in the non-volatile memory using a second storage configuration.
