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 non-volatile memory that includes multiple memory blocks, defining a redundancy zone that includes at least an old parity block, a new parity block and multiple active blocks of which one block is defined as an open block. Data is stored in the redundancy zone and the stored data is protected, such that new input data is stored in the open block, redundancy information for the active blocks including the open block is stored in the new parity block, and the redundancy information for the active blocks excluding the open block is stored in the old parity block. Upon filling the open block and the new parity block, an alternative block is assigned to serve as the open block and the new parity block is assigned to serve as the old parity block.

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.
