International Classification:

G11C 1140

US Classification:

365154

Abstract:

A static RAM cell (11) is constructed utilizing low resistivity positive and negative power supply leads (13,14), thus eliminating the problem of instability of the data stored within the cell. The negative power supply lead is formed of a first layer of low resistivity polycrystalline silicon/tantalum silicide, and the positive power supply lead is formed of a second layer of polycrystalline silicon. The use of a low resistivity negative power supply lead causes the voltage drop on the negative power supply lead to be substantially reduced as compared with prior art devices, thereby providing during the read operation substantially equal voltages to the gates of the two bistable transistors of each cell, thus eliminating the problem of instability during reading. Depletion load devices (11,12) are formed utilizing the layer of polycrystalline silicon as the source, drain and channel and the layer of polycrystalline silicon/tantalum silicide as the gate. In this manner, silicon area is not required to form the depletion load devices, thus minimizing cell size.

Abstract:

A solar tracker apparatus includes an adjustable hanger assembly that has a clam shell hanger assembly. The clam shell hanger assembly may hold a torque tube comprising a plurality of torque tubes configured together in a continuous length from a first end to a second end. A center of mass of the solar tracker apparatus may be aligned with a center of rotation of the torque tubes, in order to reduce a load of a drive device operably coupled to the torque tube. Solar modules may be coupled to the torque tubes. The solar tracker includes an energy system that includes solar panel, a DC to DC converter, a battery, and a micro-controller. The energy system may facilitate full operation movement of the tracker apparatus without any external power lines.
