    摘要: A memory has sense amplifiers that provide data onto a global data lines that are received by secondary amplifiers. The sense amplifiers and the secondary amplifiers are enabled by clocks that are timed by programmable delay circuits. The programmable delays are programmed by delay selection circuits that provide a continuous output to the programmable delay circuits. There are two delay selection circuits. One is shared by all of the programmable delay circuits that enable the sense amplifiers, and one is shared by all of the programmable delay circuits that enable the secondary amplifiers. The outputs of these two delay selection circuits are chosen to provide the output which programs the programmable delay circuits for optimizing the worst case of the access time of the memory.

    摘要: A memory has sense amplifiers that provide data onto a global data lines that are received by secondary amplifiers. The sense amplifiers and the secondary amplifiers that are coupled to the same global data lines are enabled by clocks that are timed by a common clock signal. The memory has subarrays in which each subarray is divided into blocks. When a block is selected, a corresponding block select signal is generated. The sense amplifiers and the secondary amplifiers that are coupled in common with the enabled sense amplifiers in the selected block are enabled in response to this block select signal. The block select signal that enables the sense amplifiers initiates a secondary amp control signal which, after a programmed delay, enables the secondary amplifier.

    摘要: A memory has a sense amplifier that provides data onto a global data line that is received by a secondary amplifier. The sense amplifier is precharged to a high voltage and responds to data provided by a selected memory cell on a pair of bit lines. The amplifier is a dynamic amplifier that latches the data but also limits the output voltage swing provided to the secondary amplifier. By limiting the voltage swing on the high-capacitance global data lines, there is significant power savings. The voltage swing that is provided is sufficient for reliable detection by the secondary amplifier.

    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.
