Abstract:
Apparatus, methods, and systems are disclosed, including those to improve program voltage distribution width using automatic selective slow program convergence (ASSPC). One such method may include determining whether a threshold voltage (Vt) associated with a memory cell has reached a particular pre-program verify voltage. In response to the determination, a voltage applied to a bit-line coupled to the memory cell may be automatically incremented at least twice as the program voltage is increased, until the cell is properly programmed. Additional embodiments are also described.
