International Classification:

H03K 19/003

US Classification:

326 30

Abstract:

The termination impedance of a memory agent may be selected dynamically. A transmission line may be simultaneously terminated with a first impedance at first memory agent and a different impedance at a second memory agent. A memory agent may have a terminator with at least two termination values and logic to dynamically select the termination values. Other embodiments are described and claimed.

US Classification:

725 51, 709204, 725 93

Abstract:

In particular embodiments a social networking system may receive from an external system outside the social-networking system, a request comprising a user identifier associated with a user of the social-networking system, query a social graph for stories generated by one or more connections of the user on the social-networking system, and transmit the stories to the external system. Similarly the social networking system may receive, from an external system outside of the social networking system, a request comprising a user identifier associated with a user of the social networking system, a content identifier, and a action performed by the user on the content identifier, generate a story for the received request, and publish the story to one or more connections of the user on the social networking system.

Appl. No.:

15/857535

Inventors:

- Santa Clara CA, US
Navneet DOUR - El Dorado Hills CA, US
Christopher E. COX - Placerville CA, US

International Classification:

G06F 11/273
G06F 11/27
G06F 9/448

Abstract:

A system includes test control circuitry in parallel with power control circuitry. The power control circuitry enables a core processor and memory interface drivers responsive to a reset. The test control circuitry can enable the memory interface drivers separately from the core processor to enable testing of the connections to the memory devices. The test control circuitry is triggered separately from the other power control circuitry, and can be protected to allow only secured access for testing.

Appl. No.:

15/811497

Inventors:

- Santa Clara CA, US
Arvind KUMAR - Brookline ME, US
John R. GOLES - Folsom CA, US
Christopher E. COX - Placerville CA, US

International Classification:

G06F 3/06
G06F 13/16

Abstract:

In a memory system an interface circuit includes an interface to a memory array, and to a data signal. The circuit includes loopback circuitry to enable loopback of received data signals without having to access the data from the memory array. The circuit can be part of a memory device, a register device, or a data buffer. The circuit interfaces to a memory array of a memory device, and performs loopback functions for a host controller that can test the operation of the interface.

Appl. No.:

15/364811

Inventors:

- Menlo Park CA, US
Christopher K. Cox - San Francisco CA, US

International Classification:

H04L 29/08
H04L 12/58

Abstract:

A system and method for measuring user affinity in a social network environment is provided. One or more activities performed by a user associated with a social network environment are monitored. A relationship associated with the one or more activities is identified. An affinity for one or more objects associated with the social network environment is then determined based on the one or more activities and the relationship.

International Classification:

G06F 11/30
G06F 13/40

Abstract:

Techniques and mechanisms to exchange communications via a printed circuit board (PCB) between a processor device and a memory device. In an embodiment, the processor device is configured based on a memory type of the memory device to an interface mode of multiple interface modes each corresponding to a different respective one of multiple memory standards. A voltage regulator (VR) is programmed, based on the memory type, to a VR mode to provide one or more voltages to the memory device via a hardware interface on the PCB. In another embodiment, x signal lines of an interconnect disposed in or on the PCB are each coupled between the processor device and the memory device to one another. The value x is an integer equal to a total number of signals of a superset of sets of signals each specified by a different respective one of the multiple memory standards.
