    摘要: A programmable circuit for generating a clock signal is disclosed. The present invention provides a clock generator architecture that combines PLL-based clock generator circuitry with an on-chip EPROM in a monolithic clock generator chip. The clock generator allows for electrical configuration of various information including PLL parameters, input thresholds, output drive levels and output frequencies. The various parameters can be configured after the clock generator is fabricated. The parameters can be configured either during wafer sort or after packaging. The clock generator can be erased prior to packaging so programming can be verified.

    摘要: A circuit for generating an output signal in response to an input signal that propagates over devices operating at various supply voltages. The circuit generally comprises a first device operating in a first voltage, a second device operating in a second voltage and a clamp device coupled to each of the first and second devices. The clamp device generally operates at the second supply voltage, which may cause the output signal to be propagated through the circuit with a minimum distortion.

    摘要: The present invention provides an EPROM bit-line interface with multiple functions. The invention is constructed by combining a bit/sense amplifier with two transparent latches operating on opposite edges of a timing clock. The two transparent latches form a latch and a register for holding the contents of the EPROM during power down. A bit driver is enabled when it is desirable to program the EPROM. The first transparent latch captures the contents of the EPROM when the EPROM is powered down. The first transparent latch also forms the first half of a register for shifting the contents of the EPROM to an external device. The first transparent latch operates on the leading edge of a timing clock. The second transparent latch operates on the trailing edge of a timing clock. By combining two transparent latches in series, a shift register is implemented. The shift register is used to hold the programming information while the EPROM is programmed. The shift register also holds the programming information while the contents of the EPROM are read during verification. The contents of the shift register also appear at the output of the EPROM. This eliminates the need for a multiplexer to select between the output of a shift register or the output of an EPROM during functional testing.

    摘要翻译: 本发明提供具有多种功能的EPROM位线接口。 本发明通过将位/读出放大器与在定时时钟的相对边缘上操作的两个透明锁存器组合而构成。 两个透明锁存器在掉电期间形成一个锁存器和一个用于保存EPROM内容的寄存器。 当需要编程EPROM时,位驱动程序被使能。 当EPROM掉电时,第一个透明锁存器捕获EPROM的内容。 第一透明锁存器还形成用于将EPROM的内容移位到外部设备的寄存器的前半部分。 第一透明锁存器在定时时钟的前沿工作。 第二透明锁存器在定时时钟的后沿工作。 通过组合两个透明锁存器串联,实现了移位寄存器。 移位寄存器用于在编程EPROM时保存编程信息。 移位寄存器还保存编程信息,同时在验证期间读取EPROM的内容。 移位寄存器的内容也出现在EPROM的输出端。 这消除了在功能测试期间多路复用器在移位寄存器的输出或EPROM的输出之间进行选择的需要。
