US Classification:

361760, 361789, 361684, 361790, 257684, 174250, 174267

Abstract:

An apparatus is provided, which includes a memory interface circuit, a clock signal generating circuit, and a plurality of memory circuits. The memory circuits are operatively coupled and arranged in an order on a plurality of memory modules, such that the memory module positioned at the beginning of the order is coupled to an output of the clock signal generating circuit and the memory interface circuit. The memory module that is positioned at the end of the order is unique in that it includes a clock signal terminating circuit connected to the last memory integrated circuit. With this configuration, a clock loop is formed by directly routing the clock signal from the output of the clock signal generating circuit through each of the memory modules in the order (without connecting to any of the intervening memory integrated circuits) to the memory integrated circuit positioned at the end of the order. Then, the clock signal is asserted on the previous memory modules by routing it back through the memory integrated circuits thereon, in reverse order to the memory integrated circuit positioned at the beginning of the order and from there to the memory interface circuit. To complete the clock loop, the clock signal is again asserted by routing it from the memory interface circuit back through the memory integrated circuits in order to the memory integrated circuit positioned at the end of the order.

US Classification:

257686, 257777, 257723

Abstract:

The semiconductor module is provided that includes a semiconductor housing and a plurality of integrated circuit dies positioned within the housing. The semiconductor module also includes a programmable memory device positioned within the housing and electrically coupled to the plurality of integrated circuit dies. The programmable memory device is programmable to identify the integrated circuit dies that meet a predetermined standard, such as an operating frequency requirement, or a core timing grade. Further, a method is provided for accessing a semiconductor module. The above mentioned housing is provided to enclose the plurality of integrated circuit dies and the programmable memory device. The integrated circuit dies of the plurality of integrated circuit dies that meet a predetermined standard are then identified. The programmable memory device is subsequently programmed to identify the selected integrated circuit dies.

International Classification:

Abstract:

A controller for a disk drive that accesses a look up table having a plurality of thermally characterized values corresponding to a plurality of seek operations. For each seek operation, the corresponding value is added to a register. The controller decrements the register at a rate that is determined using servo interrupts occurring as a result of the rotation of the disk. When the value of the register exceeds a threshold, the controller adjusts the subsequent seek operation so as to inhibit damage to the voice coil as a result of overheating.

International Classification:

C25D 2100

US Classification:

205 81, 204400, 204434, 205775, 205787

Abstract:

Embodiments of the invention provide an electro-analytical method for determining the concentration of an organic additive in an acidic or basic metal plating bath using an organic chemical analyzer. The method includes preparing a supporting-electrolyte solution, preparing a testing solution including the supporting-electrolyte solution and a standard solution, measuring an electrochemical response of the supporting-electrolyte solution using the organic chemical analyzer, and implementing an electro-analytical technique to determine the concentration of the organic additive in the plating bath from the electrochemical response measurements. The method is performed for independently analyzing one organic additive component in a plating bath containing multi-component organic additives, regardless of knowledge of the concentration of other organic additives and with minimal interference among organic additives.

US Classification:

360 31, 360 75, 2960309

Abstract:

A method of manufacturing a disk drive and a disk drive made with such method where the width of the read element and the width of the write element are both measured at servo-writing time and the track pitch of the disk drive is set on the basis of those measurements. Disk drives with superior head width combinations are servo-written with a narrower track pitch in order to have a higher storage capacity. Disk drives with inferior head width combinations are detected before servo-writing so that the disk drive may be servo-written with wider track pitch rather than with a nominal track pitch that results in a subsequent drive failure during initial burn-in (IBI). The heads are used more efficiently in that heads that are more capable are used to their ability and less capable heads that would otherwise be disposed of are used at all. Fewer disk drives are required to be reworked and returned to the servo-writing process.
