摘要： A method for data storage includes defining a set of scrambling sequences, each sequence including bits in respective bit positions having bit values, such that a distribution of the bit values in any give bit position satisfies a predefined statistical criterion. Each data word is scrambled using a respective scrambling sequence selected from the set. The scrambled data words are stored in the memory device.

摘要： A method for data storage includes predefining an order of programming a plurality of analog memory cells that are arranged in rows. The order specifies that for a given row having neighboring rows on first and second sides, the memory cells in the given row are programmed only while the memory cells in the neighboring rows on at least one of the sides are in an erased state, and that the memory cells in the given row are programmed to assume a highest programming level, which corresponds to a largest analog value among the programming levels of the cells, only after programming all the memory cells in the given row to assume the programming levels other than the highest level. Data is stored in the memory cells by programming the memory cells in accordance with the predefined order.

摘要： 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.

摘要： A method for data storage in analog memory cells includes defining multiple programming states for storing data in the analog memory cells. The programming states represent respective combinations of more than one bit and correspond to respective, different levels of a physical quantity stored in the memory cells. The data is stored in the memory cells by applying to the memory cells programming pulses that cause the levels of the physical quantity stored in the memory cells to transition between the programming states, such that a given transition is caused by only a single programming pulse.

摘要： A method for operating a memory (28) that includes a plurality of analog memory cells (32) includes storing data in the memory by writing first storage values to the cells. Second storage values are read from the cells, and a Cumulative Distribution Function (CDF) of the second storage values is estimated. The estimated CDF is processed so as to compute one or more thresholds. A memory access operation is performed on the cells using the one or more thresholds.

摘要： 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.

摘要： A method for data storage includes scrambling data for storage in a memory device using a given scrambling seed. A statistical distribution of the scrambled data is assessed, and a measure of randomness of the statistical distribution is computed. A scrambling configuration of the data is modified responsively to the measure of randomness, and the data having the modified scrambling configuration is stored in the memory device.

摘要： A method includes storing data in a non-volatile memory that includes multiple memory blocks. At least first and second regions are defined in the non-volatile memory. A definition is made of a first over-provisioning ratio between a first logical address space and a first physical memory space of the first region, and a second over-provisioning ratio, different from the first over-provisioning ratio, between a second logical address space and a second physical memory space of the second region. Portions of the data are compacted, individually within each of the first and second regions and independently of the other region, by copying the portions from one or more source memory blocks to one or more destination memory blocks using the first and second over-provisioning ratios, respectively.

摘要： A method includes receiving one or more storage commands and at least one flush command in a storage device, which includes a non-volatile memory and a volatile buffer for buffering data received for storage in the non-volatile memory. The flush command instructs the storage device to commit the data buffered in the volatile buffer to the non-volatile memory. The storage commands are executed in accordance with a first storage rule. The flush command is executed in accordance with a second storage rule having smaller latency relative to the first storage rule.
