    摘要: A memory cell array of dielectric charge trapping memory cells and method for performing program, read and erase operations on the memory cell array that includes bits stored at charge trapping sites in adjacent memory cells. A bit of information is stored at a first charge trapping site in a first memory cell and a second charge trapping site in a second adjacent memory cell. Storing charge at two trapping sites in adjacent memory cells increases data retention rates of the array of memory cells as each charge trapping site can be read to represent the data that is stored at the data site. Each corresponding charge trapping site can be read independently and in parallel so that the results can be compared to determine the data value that is stored at the data site in an array of dielectric charge trapping memory cells.

    摘要: A NAND-type flash memory device includes asymmetric floating gates overlying respective wordlines. A given floating gate is sufficiently coupled to its respective wordline such that a large gate (i.e., wordline) bias voltage will couple the floating gate with a voltage which can invert the channel under the floating gate. The inversion channel under the floating gate can thus serve as the source/drain. As a result, the memory device does not need a shallow junction, or an assist-gate. In addition, the memory device exhibits relatively low floating gate-to-floating gate (FG-FG) interference.
