Popis: | An electrically reprogrammable read-only-memory (REPROM) device, providing the fully decoded and on-board-writable functions, is described. The device consists of novel N -channel memory transistors with floating gate, non-volatile memory transistors, which enable electrically reprogramming operation. The memory transistor has been through more than 10 7 rewrite cycles with no gain facto (β) decrease. The memory device has been processed by the flat-MOS and the Si-gate technologies. It has a 2048 bit memory capacity, organized as 256 words of 8 bits. The polycrystalline silicon floating gate is covered with vapor-deposited silicon nitride. This allows selective write and erase operation, giving the memory device a new bit-level reprogrammable function. |
