    摘要: An integrated circuit formed of nonvolatile memory array circuits, logic circuits and linear analog circuits is formed on a substrate. The nonvolatile memory array circuits, the logic circuits and the linear analog circuits are separated by isolation regions formed of a shallow trench isolation. The nonvolatile memory array circuits are formed in a triple well structure. The nonvolatile memory array circuits are NAND-based NOR memory circuits formed of at least two floating gate transistors that are serially connected such that at least one of the floating gate transistors functions as a select gate transistor to prevent leakage current through the charge retaining transistors when the charge retaining transistors is not selected for reading. Each column of the NAND-based NOR memory circuits are associated with and connected to one bit line and one source line.

    摘要: A novel FLASH-based EEPROM cell, decoder, and layout scheme are disclosed to eliminate the area-consuming divided triple-well in cell array and allows byte-erase and byte-program for high P/E cycles. Furthermore, the process-compatible FLASH cell for EEPROM part can be integrated with FLASH and ROM parts so that a superior combo, monolithic, nonvolatile memory is achieved. Unlike all previous arts, the novel combo nonvolatile memory of the present invention of ROM, EEPROM and FLASH or combination of any two is made of one unified, fully compatible, highly-scalable BN+ cell and unified process. In addition, its cell operation schemes have zero array overhead and zero disturbance during P/E operations. The novel combo nonvolatile memory is designed to meet the need in those markets requiring flexible write size in units of bytes, pages and blocks at a lower cost.

    摘要: A nonvolatile memory array has a single transistor flash memory cell and a two transistor EEPROM memory cell which maybe integrated on the same substrate. The nonvolatile memory cell has a floating gate with a low coupling coefficient to permit a smaller memory cell. The floating gate placed over a tunneling insulation layer, the floating gate is aligned with edges of the source region and the drain region and having a width defined by a width of the edges of the source the drain. The floating gate and control gate have a relatively small coupling ratio of less than 50% to allow scaling of the nonvolatile memory cells. The nonvolatile memory cells are programmed with channel hot electron programming and erased with Fowler Nordheim tunneling at relatively high voltages.
