  • Patent number: 7529128
    Abstract: A memory architecture for an integrated circuit comprises a first memory array configured to store data for one pattern of data usage and a second memory array configured to store data for another pattern of data usage. The first and second memory arrays comprise charge storage based nonvolatile memory cells having substantially the same structure in both arrays. A first operation algorithm adapted for example for data flash applications is used for programming, erasing and reading data in the first memory array. A second operation algorithm adapted for example for code flash applications is used for programming, erasing and reading data in the second memory array, wherein the second operation algorithm is different than the first operation algorithm. Thus, one die with memory for both code flash and data flash applications can be easily manufactured using a simple process, at low cost and high yield.

  • Patent number: 7486568
    Abstract: Charge trapping memory cells are protected from over-erasing in response to an erase command. For example, in response to an erase command, one bias arrangement is applied to program charge trapping memory cells, and another bias arrangement is applied to erase the charge trapping memory cells, such that the charge trapping memory cells have a higher net electron charge, in the erased state than i.n the programmed state. In another example, an integrated circuit with an array of charge trapping memory cells has logic which responds to an erase command by applying similar bias arrangements to the charge trapping memory cells. In a further example, such an integrated circuit is manufactured.

  • Patent number: 7483307
    Abstract: A memory cell with a charge trapping structure is read by measuring current between the substrate region of the memory cell and one of the source region of the memory cell and the drain region of the memory cell. The read operation decreases the coupling between different parts of the charge trapping structure when other parts of the charge trapping structure store data that are not of interest. The sensing window of the memory cell can be greatly improved by this read operation.

  • Publication number: 20080285350
    Abstract: An architecture, circuit and method for providing a very dense, producible, non volatile FLASH memory with SONOS cells. Preferred SONOS memory cells are formed using a uniformly doped channel region. A FinFET embodiment and a planar FD-SOI embodiment cell are disclosed. Because the novel SONOS cells do not rely on diffused regions, the cells may be formed into a three dimensional array of cells without diffusion problems from subsequent thermal processing steps. FLASH memory arrays are formed by forming layers of NAND Flash cells in the local interconnect layers of an integrated circuit, with the metal layers forming the global bit line conductors. The three dimensional non volatile arrays formed of the SONOS cells rely on conventional semiconductor processing and so are easily integrated with other circuitry to form an ASIC or SoC device. P-channel and n-channel devices may be used to form the SONOS non-volatile cells.
