    摘要： A method for data storage includes storing data in a group of analog memory cells by writing into the memory cells in the group respective storage values, which program each of the analog memory cells to a respective programming state selected from a predefined set of programming states. The programming states include at least first and second programming states, which are applied respectively to first and second subsets of the memory cells, whereby the storage values held in the memory cells in the first and second subsets are distributed in accordance with respective first and second distributions. Respective first and second medians of the first and second distributions are estimated, and a read threshold is calculated based on the first and second medians. The data is retrieved from the analog memory cells in the group by reading the storage values using the calculated read threshold.

    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 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.
