    摘要: A method of embedding the forming of peripheral devices such as HV-LDMOS into the forming of flash memory is presented. A layered structure is formed with a first insulating layer formed on a substrate, and a poly silicon formed on the first insulating layer in the flash memory region. A mask layer is formed. Openings are formed in the flash memory region in the peripheral region. A local oxidation of silicon (LOCOS) is performed to form thick oxides on poly silicon, and a field oxide on silicon substrate respectively. The mask layer is removed. A control gate and a control gate oxide are formed on the thick oxide and the poly silicon. A gate electrode is formed with at least one end residing on a field oxide so that the resulting HV-LDMOS has a high breakdown voltage. Spacers and a source/drain of the flash cells and HV-LDMOSs are then formed.

    摘要: An improved memory device and the method for programming the same are disclosed. The memory device includes at least one memory block requiring a word line pre-charge time to be long enough to program one or more selected memory cells. A monitoring circuit is added for detecting one or more word lines to reach a predetermined threshold voltage to enable a predetermined high voltage to be supplied to one or more latches of the memory cells.
