    摘要: A memory circuit for holding a single binary value. A first bit cell holds one of a logical high value and a logical low value, and a second bit cell also holds one of a logical high value and a logical low value. Circuitry is provided for placing a logical high value in the first bit cell when the binary value in the memory circuit is to be a logical high value, and circuitry is provided for placing a logical high value in the second bit cell when the binary value in the memory circuit is to be a logical low value. In this manner, a logical high value exists within the memory circuit, whether the single binary value within the memory circuit is a logical high value or a logical low value. The difference between the two values of the binary value is which of the two bit cells holds the logical high value. Thus, this memory circuit can be sensed without the use of a sense amplifier.

    摘要: Non-volatile storage elements are provided in an array on an integrated circuit, where the non-volatile storage elements are low voltage CMOS devices and hence compatible in a manufacturing sense with other similar transistors on an integrated circuit. The non-volatile storage elements are either EEPROM floating gate transistor cells, or other EEPROM cells using standard low voltage CMOS devices.

    摘要: Non-volatile storage elements are provided on an integrated circuit, where the non-volatile storage elements are low voltage CMOS devices and hence compatible in a manufacturing sense with other similar transistors on an integrated circuit, thereby not requiring special types of transistors for the non-volatile storage. The non-volatile storage elements are either one-time programmable devices which are programmed by rupturing their gate oxide, EEPROM floating gate transistor cells, or other EEPROM cells.

    摘要: An in-system programing/erasing/verifying structure for non-volatile programable logic devices includes a data input pin, a data output pin, an instruction register, a plurality of data registers including an ISP register, wherein said instruction register and said plurality of data registers are coupled in parallel between said data input pin and said data output pin, and a controller for synchronizing said instruction register and said plurality of data registers. The ISP register includes: an address field, a data field, and a status field. An ISP instruction need only be entered once to program/erase the entire device. Specifically, the address/data packets can be shifted back to back into the ISP register without inserting multiple instructions between each packet at the data input pin, thereby dramatically decreasing the time required to program/erase the entire device in comparison to known ISP methods. Furthermore, the invention provides an efficient method for providing the status (i.e. result), of the ISP operations to either the end-user or the supporting software.

    摘要: A programmable logic device (PLD) includes test circuitry compatible with the JTAG standard (IEEE Standard 1149.1). The PLD also includes a programmable JTAG-disable bit that can be selectively programmed to disable the JTAG circuitry, leaving the PLD to operate as a conventional, non-JTAG-compatible PLD. The PLD also includes means for testing the JTAG test circuitry to determine whether the JTAG circuitry is defective, and means for programming the JTAG-disable bit to disable the JTAG circuitry if the testing means determines that the JTAG circuitry is defective.
