Memory management for unifying memory cell conditions by using maximum time intervals

摘要

A method includes accepting data for storage in a memory that is partitioned into multiple memory regions. A memory region is selected for storing the data. At least part of the data is stored in the selected memory region, subject to verifying that all the storage operations applied to the selected memory region are performed within a predefined maximum time interval.

1. A method, comprising:
accepting data for storage in a memory device, wherein the memory device is partitioned into a plurality of memory regions and wherein each memory region is partitioned into a plurality of memory pages; selecting a given memory region; storing a first part of the data in a first memory page of the given memory region, wherein storing the first part of the data includes performing at least a first write operation on the first memory page; recording a time stamp, wherein the time stamp is indicative of a time when the at least first write operation is applied to the first memory page; storing a second part of the data in a second memory page of the given memory region responsive to determining that a difference between a current time and the time stamp is less than a predefined maximum time interval; and closing the given memory region to additional write operations upon detecting that the predefined maximum time interval has expired since storing the first part of the data, wherein the given memory region includes storage space that is available for storage when closed.
