Fast FLASH EPROM programming and pre-programming circuit design

摘要

The programming circuit includes a voltage supply circuit coupled to a control gate and a source of a selected floating gate storage transistor. It supplies a gate programming potential across the control gate and the source in order to move charge in the floating gate. Control circuits, coupled to the voltage supply circuit vary the gate programming potential as a function of time. The voltage supply circuit includes a data-in circuit which applies a programme data voltage to a drain of the selected transistor. The gate programming potential increases during programming.
