Appl. No.:

09/686044

International Classification:

H02H 305

US Classification:

714 42

Abstract:

Memory modules such as SIMMs and DIMMs are automatically tested by a target-system motherboard such as a PC motherboard. An automated SIMM/DIMM handler is connected to a handler adaptor board that is mounted to the back or solder-side of the PC motherboard. The relatively flat surface of the solder-side of the PC motherboard allows close mounting of the handler. One or more of the SIMM sockets on the motherboard is removed to provide mounting holes for the handler adaptor board. The handler adaptor board provides electrical connection from the module-under-test (MUT) in the handler to the removed SIMM socket on the PC motherboard. The handler adaptor board provides a slight spacing or offset from the solder-side surface of the PC motherboards substrate, allowing the handler to be plugged directly into tester-connectors on the handler adaptor board. Since the offset of the adaptor board is slight, the length of electrical connections to the handler is short, minimizing the load on the PCs memory bus. A handler controller card that controls the handler is plugged into the PCI or ISA bus on the PC motherboard.

US Classification:

360 75, 360 7808

Abstract:

A disk drive is disclosed comprising a disk having a plurality of servo sectors defining a plurality of servo tracks, wherein each servo sector comprises a track address identifying a corresponding servo track. A head is actuated over the disk, and a ramp is positioned near an outer diameter of the disk, wherein an edge of the ramp extends over a plurality of the servo tracks. The head is loaded from the ramp onto the disk, and a track address in at least one of the servo sectors is detected and stored. The process is repeated a number of times, and then a starting track proximate an outer diameter of the disk is identified in response to the detected and stored track addresses.

International Classification:

G11C 7/00

US Classification:

36518911, 365222

Abstract:

A memory module is disclosed. The memory module comprises a voltage supply; a memory interface coupled to the voltage supply; a plurality of memory components; and a voltage stabilizer converter (VSC) coupled to the memory interface and to the plurality of memory components, the VSC for ensuring that the plurality of memory components operate at their optimum performance level. A voltage stabilizer memory module (VSMM) in accordance with the present invention includes a printed circuit board (PCB) that contains memory chips, discrete components, a voltage stabilizer converter, and other related components. The voltage stabilizer converter uses system voltage supply as its input and its output is the voltage supply for the DRAM components. Accordingly, the VSSM is more adaptable, more stable and has better performance than conventional memory modules.

Abstract:

A diagnostic extender card is plugged into a memory module socket on a personal computer (PC) motherboard. The extender card has a test socket that receives a memory module and an intercepting decoder chip that receives the chip-select (CS) from the motherboard that selects the memory module for access. When CS is activated, the intercepting decoder chip illuminates a visual indicator on the extender card, allowing a user to locate a memory module being accessed. The exact translation or mapping from logical addresses of test programs to physical addresses of the memory modules is not needed, since the visual indicator shows which memory module is really being accessed, regardless of proprietary address mapping by north bridge chips. Operating system memory accesses are filtered out by a counter that counts accesses during a period set by a timer. When the number of accesses exceeds a threshold, the visual indicator is lit.
