摘要:
A low standby current power-on reset circuit is described. A first NMOS transistor's drain is coupled to a first PMOS transistor's drain; source coupled to ground line; and gate coupled to a first capacitor coupled to ground line. The first PMOS transistor's source is coupled to power line; gate coupled to second capacitor coupled to ground line; and drain provides a power-on reset indication. A second PMOS transistor's source is coupled to power line; drain is coupled to drain of second NMOS transistor, gates of first PMOS, second PMOS, and second NMOS transistors, and second capacitor. The second NMOS transistor's source is coupled to gate of first NMOS transistor and first capacitor. A discharge circuit is coupled to power line, ground line, and first and second capacitors for discharging the capacitors when a voltage on power line drops below a level determined by the second PMOS transistor's threshold voltage.

An OTP bit cell includes a latch circuit of cross-coupled inverters. A floating gate PMOS transistor is inserted in each of the inverters. One or the other of the floating gate PMOS transistors is programmed through an included programming circuit so that a differential output of the latch circuit provides a corresponding logic state that is the same each time when read. To program a selected floating gate PMOS transistor, appropriate write inputs are applied to the programming circuit while a high reference voltage to the OTP bit cell is raised to a level such that the selected floating gate PMOS transistor is programmed.

A dynamic random access memory 400 includes an array 401 of physical rows and columns of memory cells, the cells of each row coupled to first and second wordlines 603 and first and second bitlines 602. A direct input/output data path 402 having a width equal to a width of the rows supports simultaneous writing to each of the cells along a selected row using the first wordlines and first bitlines during a single access cycle without restore.

The present invention relates to a cushioning device for supporting a large animal such as a cow or a horse. The cushioning device comprises a top surface, a bottom surface, said top surface and bottom surface forming a chamber, and an amount of a gelatinous filling material disposed within the chamber. The present invention relates also to methods of transporting and installing a cushioning device for supporting a large animal. The method comprises transporting the cushioning device and a compound capable of creating a gel upon contact with a liquid may be delivered separately to the site. At the remote site the compound may be disposed within the chamber and the chamber may then be filled with an amount of liquid to create the gel within the cushioning device. The compound may also be delivered to the site already disposed within the chamber.

A dual-plenum showerhead for semiconductor processing operations is provided. The showerhead may include a faceplate with two sets of gas distribution holes, each set fed by a separate plenum. One set of gas distribution holes may be through-holes in the faceplate of the showerhead and may allow gases trapped between the faceplate and a plasma dome to flow towards a wafer. The other set of gas distribution holes may distribute gas routed through passages or channels in the faceplate towards the wafer. The passages or channels in the faceplate may include radial channels and annular channels and may be fed from an annular gas distribution channel about the periphery of the faceplate.

The invention is concerned with new approaches to cooling processing equipment in data centers. A cooling system is described herein that is suitable for cooling processing equipment in data centers. The cooling system includes a vertical conduit carrying a cooling liquid and an array of elongate heat conducting elements, such as heat pipes, extending laterally outwardly from the conduit. An inner end portion of each heat conducting element is in thermal contact with cooling liquid flowing in the conduit and an outer end portion of each heat conducting element is adapted for conductive thermal contact with at least one heat producing electronic component.
