Abstract
A memory apparatus includes memory cells connected to word lines and operable in one of a first read condition in which a word line voltage of the word lines is discharged and a second read condition in which the word line voltage of the word lines is coupled up to a residual voltage level. A control means is coupled to the word lines and is configured to program the memory cells in a program operation. Following programming of the memory cells connected to specific ones of the word lines, the control means is also configured to apply a predetermined dummy read voltage to the specific ones of the word lines during a dummy read operation to maintain the memory cells connected thereto in the second read condition, the specific ones of the word lines determined based on an amount of the memory cells that are programmed.
