Title: Method and device for programming and stabilizing multilevel cell flash memory device
Inventor: DI ZENZO MAURIZIO
IPC: G11C16/02
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To keep a parallelism of a memory array by setting each of many possible states to meet a permissible range for a threshold voltage of a cell transistor and setting each of the permissible ranges by a pair of reference voltages. SOLUTION: Each stage of the programming is carried out by connecting an AND gate 3 to a pulse generator 1, whereby pulses are applied to each cell 4 for a specific number of times in accordance with a characteristic of the cell. The pulses appear at an output of the corresponding gate 3 only when the cell is enabled by a signal from a counter 5 correspondingly started appropriately. An impulse amplitude determining an amount of injected charges, a threshold voltage as a result of the charges and a stored data selects a specific source resistor 6 executed through a switch 7, so that the cell 4 is controlled. The cell is programmed until the amount of charges injected to a floating gate generates the threshold voltage of a value within a permissible range.
