Embodiment Construction

[0086] The following description of the preferred embodiment(s) is exemplary only, and is not intended to limit the invention, its application or uses. For purposes of clarity, the same reference numbers will be used in the drawings to identify similar elements. As used herein, the term module refers to an application-specific integrated circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group) and memory, a microprocessor subsystem, a combination of Logic circuits, compound logic macros, and / or other suitable components that provide the described functionality.

[0087] Referring to FIGS. 1A and 1B , the present invention enables groups of devices (eg, composite logic macros and / or modules) to be stacked on top of each other to overcome practical parasitic resistance barriers. In FIG. 1A, composite logic macros 20 and 24 are stacked on top of each other and are connected at V DD and V L between. In some implementations, V L Can be land. In FIG. 1B...

Abstract

The invention provides a low voltage logical operation which uses supply electrical level with higher pressure. Network equipment comprises a first communication channel module, a second communication channel module which is connected in series with the first communication channel module, a third communication channel module which is connected in series with the second communication channel module and a fourth communication channel module which is connected in series with the third communication channel module. The first communication channel module and the fourth communication channel are connected between a first reference potential and a second reference potential. The first reference potential, the second reference potential, the third communication channel and the fourth communication channel module are equal in functions.

Description

technical field [0001] The present invention relates to the operation of low voltage complex logic macros and / or modules using higher voltage supply levels and lower current levels. Background technique [0002] Over the past decade, complementary metal-oxide-semiconductor (CMOS) processes have resulted in smaller devices by integrating higher numbers of transistors. For example, current microprocessors are more than a thousand times more powerful than those manufactured a decade ago. [0003] The power consumption of microprocessors is also increasing. Today, some microprocessors consume more than 100W. Modern processors built using low-voltage CMOS processes use supply voltage levels that rarely exceed 1V. As a result, CMOS-based microprocessors require current levels in excess of 100A. [0004] Physical barriers begin to limit the amount of current that can flow through these devices. One obstacle involves the voltage drop associated with the distribution of power in...
