  • Publication number: 20040109380
    Abstract: A novel structure of nonvolatile memory is disclosed. The nonvolatile memory includes two serially connected PMOS transistors. The characteristic of the devices is that bias is not necessary to apply to the floating gate during the programming mode. Thus, the control gate is omitted for the structure or layout, thereby saving the space for making the control gate. The carrier may be “automatically injected” into floating gate for programming the status of the devices.

    Abstract: A flash memory array and related method for programming, erasing, and reading. The memory includes: a plurality of memory cells, each memory cell having a gate, a drain, a source, and a body; a plurality of word lines and body lines. The bodies of the memory cells whose gates are connected to a same word line are connected to a same body line, and the body lines are isolated from each other such that different body lines can be driven to have different voltages. When the memory programs, erases, and reads data, the different body lines are driven to different voltage.

  • Publication number: 20040099914
    Abstract: A low-voltage nonvolatile memory array includes an N type semiconductor substrate having a memory region. A deep P well is formed in the semiconductor substrate. A cell N well is located within the memory region in the semiconductor substrate. The cell N well is situated above the deep ion well. A shallow P well serving as a buried bit line is doped within the cell ion well. The shallow P well is isolated by an STI layer, wherein the STI layer has a thickness greater than a well depth of the shallow ion well. At least one memory transistor with a stacked gate, a source, and a drain is formed on the shallow ion well. The source of the memory transistor is electrically coupled to the cell N well to induce a capacitor between the cell N well and the deep P well during a read operation, thereby avoiding read current bounce or potential power crash.

  • Publication number: 20040093690
    Abstract: A hinge for a notebook computer is composed of a first seat, a second seat and an axle. The first seat is mounted on a monitor, and the second seat is mounted on a body. The axle is securely mounted on the first seat and pivotally mounted on the second seat. Two sleeves are provided outside the axle and engaged with each other in a closed status. The first sleeve has two lugs received in a channel defined in the second sleeve. The second sleeve has two protrusive portions respectively formed at two sides of the channel, and two cambered surfaces formed between the channel and the protrusive portion. When a user lowers the monitor to a position that the lugs enter into the cambered surfaces, the monitor can automatically descend under the effect of gravity and the force of a resilient member.

  • Patent number: 6717206
    Abstract: The present invention relates to a structure of an embedded channel write/erase flash memory cell and a fabricating method thereof and, more particularly, to a structure combining CMOS devices and flash memory cells, wherein flash memory cell structures and CMOS devices are simultaneously fabricated on a substrate to reduce the cost and to simplify the process flow. Moreover, CMOS devices capable of performing high-voltage and low-voltage operations are reserved. Therefore, the present invention can not only effectively improve the operating efficiency of flash memory cells and CMOS devices, but its whole volume is also smaller than that obtained by combining separately designed and fabricated CMOS devices and flash memory cells.
