Abstract
A non-volatile memory system includes technology for detecting read disturb in open blocks. In one embodiment, the system determines whether a particular block of non-volatile memory cells has been subjected to a minimum number of open block read operations and performs sensing operations for memory cells connected to an open word line of the particular block. The number of errors in the sensed data is determined. If the number of errors is greater than a limit, then the system takes an action to mitigate the read disturb.
