摘要： A Flash memory system and a method for data management using the system's sensitivity to charge-disturbing operations and the history of charge-disturbing operations executed by the system are described. In an embodiment of the invention, the sensitivity to charge-disturbing operations is embodied in a disturb-strength matrix in which selected operations have an associated numerical value that is an estimate of the relative strength of that operation to cause disturbances in charge that result in data errors. The disturb-strength matrix can also include the direction of the error which indicates either a gain or loss of charge. The disturb-strength matrix can be determined by the device conducting a self-test in which charge-disturb errors are provoked by executing a selected operation until a detectable error occurs. In alternative embodiments the disturb-strength matrix is determined by testing selected units from a homogeneous population.

摘要： A Flash memory system and a method for data management using the embodiments of the invention use special test cells with Early Degradation Detection (EDD) circuitry instead of using the actual user-data storage cells are described. The Flash memory test cells can be made to serve as a “canary in a coal mine” by being made more sensitive than the standard cells by using experimentally determined sensitive write VT and variable read VT. Techniques for early degradation detection (EDD) in Flash memories measure the dispersion of the threshold voltages (VT's), of a set (e.g. page) of NAND Flash memory cells during read operations. In an embodiment of the invention the time-to-completion (TTC) values for the read operation for the memory cells are used as a proxy for dispersion of the threshold voltages (VT's). A Dispersion Analyzer determines the dispersion of the set of TTC values.
