Patent number: 7596028Abstract: Methods for programming and program verification of a flash memory are described that ease the buried drain contact induced operation and increase the retention window. In a first aspect of the invention, a program operation method provides varying program biases which are applied to different groups of memory cells. The program biases can be supplied as drain bias voltages or gate bias voltages. The program biases vary depending on which group of memory cells is programmed. In one embodiment, a first drain voltage VD1 is applied to the first group of memory cells M0 and Mn. A second drain voltage VD2 is applied to the second group of memory cells M1 and Mn-1, where VD2=VD1+?VD. In a second aspect of the invention, a plurality of program verification voltage levels are selected to verify that the memory cells pass the program voltage levels.Type: GrantFiled: December 28, 2006Date of Patent: September 29, 2009Assignee: Macronix International Co., Ltd.Inventors: Ming Shiang Chen, Wen Pin Lu, I-Jen Huang, Chi Yuan Chin, Nian-Kai Zous

Patent number: 7187590Abstract: A process and a memory architecture for operating a charge trapping memory cell is provided. The method for operating the memory cell includes establishing a high threshold state in the memory cell by injecting negative charge into the charge trapping structure to set a high state threshold. The method includes using a self-converging biasing procedure to establish a low threshold state for the memory cell by reducing the negative charge in the charge trapping structure to set the threshold voltage for the cell to a low threshold state. The negative charge is reduced in the memory cell by applying a bias procedure including at least one bias pulse. The bias pulse balances charge flow into and out of the charge trapping layer to achieve self-convergence on a desired threshold level. Thereby, an over-erase condition is avoided.Type: GrantFiled: June 24, 2004Date of Patent: March 6, 2007Assignee: Macronix International Co., Ltd.Inventors: Nian-Kai Zous, Wen-Jer Tsai, Hung-Yueh Chen, Tao Cheng Lu

Patent number: 6812099Abstract: A method for fabricating a non-volatile memory having a P-type floating gate is described. A tunneling layer is formed on a substrate and then a first patterned polysilicon layer is formed on the tunneling layer. A buried drain is formed in the substrate beside the first polysilicon layer and then an insulating structure is formed on the tunneling layer on the buried drain. Thereafter, a second polysilicon layer is formed on the first polysilicon layer to constitute a floating gate together with the first polysilicon layer. A P-type ion is implanted into the second polysilicon layer and then a dielectric layer and a control gate are sequentially formed on the floating gate. A thermal process is then performed to make the P-type, ion in the second polysilicon layer diffuse into the first polysilicon layer.Type: GrantFiled: May 2, 2002Date of Patent: November 2, 2004Assignee: MACRONIX International Co., Ltd.Inventors: Hung-Sui Lin, Nian-Kai Zous, Tao-Cheng Lu, Kent Kuohua Chang
