Abstract
A writing circuit for a non-volatile memory apparatus is provided. The non-volatile memory apparatus includes a control circuit determining that a programming process of each memory cell is finished when performing data writing. An on/off state of a first switch is controlled according to data stored by a memory component, wherein the memory component stores a programming verify status of the corresponding memory cell. A determination control MOS transistor performs a determination control on a programming validation. A second switch applies a voltage for controlling the determination control MOS transistor to a gate of the determination control MOS transistor according to a determination control signal and sets a gate voltage of the determination control MOS transistor to a voltage value equal to a threshold voltage of the determination control MOS transistor plus a predetermined control voltage value.
