摘要： A portable information storage and transfer device for use with IC memory card-based portable computers performs many data transfer operations. The floppy disk drive in the information storage and transfer device allows large amount of data and software programs to be made available to the IC memory card-based computer on floppy disks. The contents of such floppy disk can then be transferred for use in the portable computer on a blank IC memory card or the portable computer's system memory. Information entered into and stored in the system memory or an IC memory card of the portable computer can also be transferred through the information storage and transfer device to floppy disks, to a printer, to various peripheral devices or to a host computer. A built-in modem for accessing facsimile machines, other modems and the telephone system is also provided. Many types of software programs required to enable these functions of information storage, transfer, printout and communication stored locally rather than on IC memory cards, and read into the information storage and transfer device on demand.

摘要： A portable information storage and transfer device for use with integrated circuit (IC) memory card-based palmtop computers obviates many operations traditionally requiring a desktop computer. An external floppy disk drive allows large amount of data and software programs to be made available to the IC memory card-based computer on floppy disks. In addition, two memory card slots are provided to allow reading and writing IC memory card under either the proprietary format of the palmtop computer or an industry standard format, such as Personal Computer Memory Card International Association (PCMIA). Data interchange is thus between media written under disparate operating systems, file structures and basic input/output structures.

摘要： Disclosed herein is a structure and process for a self-aligned metal semiconductor field effect transistor having the characteristics of a high speed, high density, low power LSI circuit and specifically an improved high device gain MESFET device using conventional photographic techniques. The inventive MESFET device has improved high device gain as a result of the elimination of series resistance, increased circuit integration density, and improved speed capability due to the elimination of spacings between gate and drain and gate and source and the improved high device gain.

摘要： A semiconductor structure and particularly a high-speed VLSI self-aligned Schottky Metal Semi-Conductor Field Effect Transistor having a relatively high operating frequency and low series resistance, predicated upon very controllable small structure geometries made by the growth of oxide bumper insulators on either side of the schottky barrier. The oxide bumpers width is relatively thicker than the depth of the initial silicon dioxide layer on the substrate surface thereby providing effective separation of the gate from the source and drain respectively. Accordingly, spatial separations between the self-aligned gate-and-drain and gate-and-source can be relatively very closely controlled by varying the doping level of an intermediate polysilicon layer thereby providing controllable differential polysilicon oxidation rates for the bumpers. Thus, the series resistance can be controlled to be relatively low thereby providing a VLSI SASMESFET device that can be operated at relatively high speeds.
