摘要: The present invention provides a novel operational method of twin MONOS metal bit or diffusion bit structure for high-speed application. In a first embodiment of the present invention, the alternative control gates are set at the same voltage. In a second embodiment of the present invention, all the control gates are set at the operational voltage from the beginning. In both embodiments, the bit line and word gate are used to address the selected memory cell.

摘要: A reference circuit is described for creating a reference signal using a twin MONOS memory cell. A first portion of the twin MONOS memory cell connects to a charged and floating bit line a current source formed in a second portion of the twin MONOS cell that discharges the charged bit line to form a reference signal for a sense amplifier. The sense amplifier compares the reference signal to a signal from a selected memory cell upon which memory operations are being performed comprising read, erase verify and program verify.
