| Abstract | Disclosed is an apparatus and method for determining a parameter for programming a non-volatile memory circuit. On receiving write or erase operation a parameter is determined as a function of a circuit characteristic associated with a memory block. An adjusted condition, for example, read or write time, or the standard deviation of voltage thresholds in a distribution of cells, is then determined as a function of the parameter, and a command provided to the memory circuit to use the parameter in the next write or erase operation performed on the memory block. The method can be triggered by an event such as P/E cycle times and the condition is dynamically adjusted to extend the life of the memory circuit. |
