ABSTRACT:
In a digital memory system, systems and methods that control a logical value and an integrity of data represented by charge are provided. In one embodiment, a bit line is coupled to the cell. A voltage generator is arranged to generate a plurality of cell operating voltages varying in response to a voltage control signal. A controller generates a control signal, stores a predetermined one of logical values in a cell by generating a series of operating voltages, transmits the series of operating voltages, and determines whether the predetermined one of the logical values has been stored in the cell in response to a voltage on the bit line. The controller includes a charge integrity estimating module and determines whether the predetermined one of the logical values has been stored in the cell by initiating the operation of the charge integrity estimating module.
