Ordering of parallel data storage based on die programming durations

摘要

A method includes, in a memory system that includes multiple memory units, holding information indicative of respective programming durations of the memory units. Data is stored in a stripe that includes a plurality of the memory units, by programming the memory units in the stripe in an order that is set based on the information.

1. A method, comprising:
in a memory system that stores data in a memory, estimating respective actual programming durations of memory units of a given bit significance, which vary statistically among the memory units of the given bit significance; and storing data in a stripe that comprises a plurality of the memory units of the given bit significance, by programming the memory units in the stripe, all having the given bit significance, in an order that is set depending on the actual programming durations.
