摘要： A method and system of accessing memory cells within a dynamic hardware memory block operated with a bitline precharge circuit, in which differential read/write access operations are performed by activating complementary bitlines. A reduction in power dissipation is realized by determining whether a next access operation following a current access operation is a read or write access, and performing a precharge of the bitlines of the array only when a read operation follows the current access operation. A conventional precharge control signal is combined with an external control signal indicating if the next cycle is a read cycle. The combination of the two signals can be used, for example, as input to a simple AND gate to generate an effective precharge signal. The effective precharge signal permits precharging of bitlines only when those bitlines are used for read access in a respective next cycle.

摘要： A multi-port (e.g., two port) CMOS static random access memory (SRAM) with a local clock driver generating clocks for boundary latches. Local clocks select between address inputs clocked into the boundary latches. A read clock selects and latches a read address in the boundary latches. A second clock latches write addresses and, when appropriate, test data addresses.

摘要： A clock stretcher mechanism is provided for shifting a rising edge of a negative active global clock signal beyond a rising edge of a feedback path signal. A negative active global clock signal and a clock chopper signal are received in a base block. First base block circuitry modifies the clock chopper signal in order to form the feedback path signal. Second base block circuitry shifts the rising edge of the negative active global clock signal beyond the rising edge of the feedback path signal using a delay negative active global clock signal.

摘要： A pulsewidth modulation circuit uses a plurality of programmable paths to connect its output line to ground connections. The paths have different numbers of serially-connected NFETs to provide different pulldown rates. A desired programmable paths is selected based on encoded control signals, with decode logic integrated into the programmable paths. The decode logic includes, for each path, at least two transistors controlled by one of the encoded signals or their complements. A default path to ground may also be provided for use when none of the programmable paths is selected. For example, two encoded signals may be used to select 1-in-4 among the default path and three programmable paths. Integration of the decode logic into the programmable paths results in smaller overall circuit area, leading to reduced power usage, while still retaining the orthogonal benefit of encoded control signals.
摘要翻译： 脉宽调制电路使用多个可编程路径将其输出线连接到接地连接。 这些路径具有不同数量的串联NFET，以提供不同的下拉速率。 基于编码的控制信号选择所需的可编程路径，其中解码逻辑集成到可编程路径中。 对于每个路径，解码逻辑包括由编码信号之一或其补码控制的至少两个晶体管。 当没有选择可编程路径时，还可以使用默认的接地路径。 例如，两个编码信号可用于在默认路径和三个可编程路径中选择1到4。 将解码逻辑集成到可编程路径中导致较小的总电路面积，导致功率消耗的降低，同时仍然保持编码控制信号的正交优点。
