Abstract
The present invention provides a method and system to reduce the impact of errors introduced in flash devices while providing improved system performance through optimized activities with limited impact to overhead using a predetermined threshold value or threshold device value. In an embodiment, a device threshold value is compared with the cumulative number of data bits having a zero value of a target page and an error type of the target page is assessed to determine whether the target page is available to be written to. Therefore for a highly effective method for is provided for determining the availability of a page, having a block address and page address, to be identified, in one instance, as being an erased page that is available to be written to.
