Method to avoid malconnections with respect to voltage levels of electronic components of circuit boards during circuit board design

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.

Power saving by disabling cyclic bitline precharge

The present invention relates to the field of hardware logic circuits and in particular to dynamic hardware logic implemented in computer processors, and more particularly, to an integrated circuit comprising a dynamic logic function implementing a predetermined logic function with a plurality of transistor stacks, the integrated circuit comprising a precharge node at the input of said logic function implementation, an output latch connected to the output node of said logic function for stabilizing the result of the evaluation of said logic function. The present invention provides such integrated dynamic circuit with a latch, which is protected against instability even in situations involving complex logic functions which are evaluated and their output states are saved by said output latch.

Midcycle latch for power saving and switching reduction

A cable connector assembly and method for making, wherein the assembly connects to a flat ribbon cable having a plurality of conductors and electrical insulation about the conductors. The cable connector assembly includes a plurality of electrical contacts, each including a terminal configured to connect to at least one of the conductors of the flat ribbon cable directly through the electrical insulation to form an electrical junction. Each contact is configured to electrically connect to an external member. The cable connector assembly has a housing for holding the contacts arranged in a first row and as second row where the contacts in the rows form a grid and are connected in an offset manner to minimize cross talk.
