    摘要： An input block for PLDs programmable logic devices) has a flip-flop including a master latch and a slave latch, a pad for inputting data, configuration bits, and a global clock input signal for clocking the input data to the flip-flop means. The flip-flop is controlled by the configuration bits so as to function alternatively as a register, a latch or transparently. The input block further includes at least one clock enable signal input terminal and logic elements responding to the configuration bits for providing the clock enable signal for the register function as well as the latch function of the flip-flop.

    摘要： A complex programmable logic device (PLD) that includes a number of programmable function blocks and an instruction bus for receiving programming instructions. The programming instructions are used to program the function blocks to enable the PLD to perform one or more desired logic functions. The PLD also includes an instruction-blocking circuit that is connected to each of the functional blocks. When directed by a user, the instruction blocking circuit selectively blocks programming instructions on the instruction bus from one or more of the function blocks while allowing the other function blocks to receive the programming instructions. Thus, one or more function blocks in the PLD are reprogrammed without interrupting the operation of the remaining function blocks.

    摘要： More than one security bit is used in a block of a PLD chip. The internal configuration and other information is left unprotected when all the security bits are in the erased state, and is protected by programming one or all the security bits. The security bits are located physically in proximity to the areas containing configuration and any other user-defined data, both so that they are difficult to discover and so that the erasure of all security bits in a EPROM-based PLD would cause a large number of adjacent user-defined bits to be erased as well, hence making it very difficult to extract useful information from a protected device by reverse engineering. Situating security bits in a different, pseudorandom location within each block of the chip makes them difficult to find and so further inhibits reverse engineering.

    摘要： A memory device, with increased storage speed and enhanced memory utilization, can be implemented by using multiplex clocking and efficient device design and enhanced flip-flop utilization. Transit time through the circuit, and hence circuit speed, can be controlled through multiplexed clock signals, and is increased by using fewer transistors in the signal path and allowing data to be transmitted directly to the flip-flop output by bypassing the flip-flop's master latch input.
