Title:
NOVEL NON-VOLATILE MEMORY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/079991
Kind Code:
A1
Abstract:
The present invention relates to a novel non-volatile memory and a manufacturing method therefor. The novel non-volatile memory comprises a selection transistor and a storage transistor, and the selection transistor comprises a gate oxide layer and a first logic gate. The novel non-volatile memory of another structure comprises a storage transistor, and the storage transistor comprises a tunneling dielectric layer, a floating gate, a second inter-gate dielectric layer, and a second logic gate which are sequentially provided. According to the memory of the present invention, by replacing a conventional control gate with the logic gate, the manufacturing process of the memory is simpler, the use number of photomasks is reduced, and the manufacturing cost is further reduced.
