摘要： Methods and apparatus for dynamically adjusting the amount of power (or current) distributed to one or more connected devices via electrical interfaces. In one embodiment, the apparatus comprises a first module adapted to detect current drawn by a first set of ports, and a second module adapted to adjust the current provided to a second set of ports based on the detected current. The second module is also optionally adapted to distribute unreserved current among the devices according to an allocation protocol. In the exemplary context of a plurality of interconnected serial bus devices, the invention enables a device to draw more current than that required to be reserved for that device (such as to comply with a specification such as USB), yet without increasing the total amount of power which must be dedicated to the serial ports as a whole. Power supply efficiency may also be advantageously optimized.

摘要： A power-on reset circuit (30) for a memory (20) includes a DC model circuit (39), an N.sub.BIAS check circuit (64), and a NAND logic gate (71). A logic low power-on reset signal is provided at power-up of the memory (20) to establish initial conditions in a clock circuit (29) and in row and column predecoders/latches (24, 27). When the power supply voltage, a bandgap reference voltage, and a bias voltage all reach their predetermined voltages, the power-on reset circuit (30) provides a logic high power-on reset signal. In this manner, the power-on reset circuit (30) is assured of providing a logic low power-on reset signal until all of the proper voltage levels are reached. In addition, the power-on reset circuit models a DC circuit equivalent of an address buffer circuit (79) for compensating for process and temperature variations.

摘要： A delay locked loop (44) includes an arbiter circuit (86), a VCD circuit (85), and a collapse detector (88). The arbiter circuit (86) receives an input signal and provides a retard signal to adjust the amount of propagation delay of VCD circuit (85), in order to synchronize the phases of the input signal to an output signal of the VCD circuit (85). The collapse detector (88) detects if the output signal of the VCD circuit (85) has failed to change logic states within a predetermined length of time. The delay locked loop (44) can lock the phases of two signals having different frequencies.

摘要： A pipelined memory (20) has a synchronous operating mode and an asynchronous operating mode. The memory (20) includes output registers (34) and output enable registers (48) which are used to electrically switch between the asynchronous operating mode and the synchronous operating mode. In addition, in the synchronous operating mode, the depth of pipelining can be changed between a three stage pipeline and a two stage pipeline. By changing the depth of pipelining, the memory (20) can operate using a greater range of clock frequencies. In addition, the operating frequency can be changed to facilitate testing and debugging of the memory (20).
