Abstract
A system for improving utilization of a nonvolatile flash memory device which has pages whose guaranteed per-cycle erase time and guaranteed number of cycles are known, the system comprising erase time determination functionality for individual pages; de-facto total erase-time accumulation functionality incrementing, for each erase cycle to which an individual page is subjected, by the individual page's de facto erase time per cycle as provided by the erase time measurement functionality; and flash memory page usage monitoring functionality operative to control usage of pages in flash memory including selecting at least one individual flash memory page depending on a comparison between the individual flash memory page's de facto total erase time and a guaranteed erase time computed as a product of the guaranteed per-cycle erase time and of the guaranteed number of cycles.
