Abstract
Method and apparatus for managing data in a memory, such as a flash memory array. In accordance with some embodiments, a block of solid-state non-volatile memory cells are each programmed to an associated programmed state responsive to a respective amount of accumulated charge. A charge loss compensation circuit adds a relatively small amount of additional charge to the respective amount of accumulated charge in each of the memory cells to maintain the associated programmed states of the cells.
